Added a new F\# example (main.fsx) that defines an 'Undefined' exception type and uses it to create several type aliases (CustomerInfo, ShippingAddress, etc.) and a record type (Order). In the Go example, removed the commented-out F\# type definition and added a newline character to the Printf format string.

Added a new F\# script (main.fsx) demonstrating how to model simple values using single-case unions and pattern matching. In the Go example, the main function was refactored to remove commented-out code and unused variable declarations, simplifying the demonstration of value types.

Removed all files in the 'WORKING' directory, which contained experimental Go code demonstrating functional programming concepts such as higher-order functions, currying, functional composition, and pipeline patterns.

The repository now includes an MIT license file, clarifying the terms of use and distribution for the software. Additionally, the README has been updated to correct the author's name from 'Scott Wlashin' to 'Scott Wlaschin' in the description of the domain modeling port.

Added compile-time checks to ensure that EmailContactInfo, PostalContactInfo, and BothContactMethods correctly implement the ContactInfo interface. This prevents runtime errors by verifying interface satisfaction at compile time, improving code reliability without runtime overhead.

The main.go file in the 108-invariant directory has been refactored to remove large blocks of commented-out code and unused type definitions. This cleanup improves code readability and maintainability by eliminating dead code that was previously present in the file.

The text message printed when a paid invoice is processed has been corrected from 'The paid invoiceis is' to 'The paid invoice is is'. This fixes a typo in the user-facing output string.

The 085-workflows-struct example was updated to include a newline character in the output of the placeOrder function, ensuring the printed result is properly terminated.

The 107-units-of-measure example was updated to correct a type mismatch error. The code previously attempted to assign a string value to a variable typed as a custom float64-based unit, which is invalid in Go. This change removes the invalid assignment, ensuring the example compiles and runs without type errors.

The main Go source file for the 108-invariant2 example has been moved from the 'WORKING' directory to the root of the 108-invariant2 folder. This change reorganizes the project's file structure, ensuring the entry point is located in the expected location for the example.

The Go source files for the 110-capturing-rules example have been relocated from the 'WORKING' subdirectory to the root of the project. This change also includes minor cleanup of comments and removal of extraneous reference material.

The domain modeling examples have been refactored to better illustrate type composition and pattern matching. In the F\# examples (065, 067, 068), the code now explicitly defines sum types (unions) and record types, with 067 demonstrating a discriminated union for order quantities and 068 showing a complex payment type composed of other types. In the Go examples, the code has been cleaned up by removing commented-out F\# code and unused test functions, while enabling the \ConvertPaymentCurrency\ function to show the practical application of the composed \Payment\ type.

065-sum-types, 067-sum-types, 068-composing-types · medium confidence

The commented-out type alias for InvoiceId has been removed from the main.go file, cleaning up the codebase by eliminating unused or obsolete type definitions.

The main.go file for the '086-workflows-sum-switch' example has been moved from the 'WORKING' directory to the root of the example folder. This reorganization likely reflects a change in the project's directory structure or workflow management.

The entity identifier types have been simplified: ContactId is now defined as an empty interface rather than a custom type wrapping a UUID, and the UUID generation output formatting has been adjusted to remove an extra space in the printed string.

089-entity-identifiers · medium confidence

The main function's logic was streamlined by removing several commented-out code blocks and unused variable declarations. Debug print statements for variables 't' and 'b' were updated to include explicit labels, and the conditional check that previously initialized 't' via 'createSession' was commented out, effectively disabling that initialization path.

109-invariant3 · medium confidence

The Go implementation for the '032-intro' location now actively processes and prints the results for shipping and billing addresses, which were previously commented out or missing. Specifically, the \main\ function now instantiates \ShippingAddress\ and \BillingAddress\ structs and passes them to the \do\ function, allowing users to see how these specific data structures are handled within the Order-Taking bounded context.

The import path for the immutable value object package has been updated from 'github.com/088-value-objects/immutable/valueobject001' to 'github.com/gbih/ddd-in-go/088-value-objects/immutable/valueobject001'. This change ensures the code references the correct repository location for the value object implementation.

The Go module definitions have been restructured. The module at '105-private' was removed entirely. The module at '088-value-objects' was renamed and its module path was updated from 'github.com/088-value-objects/immutable' to 'github.com/gbih/ddd-in-go/088-value-objects/immutable'. The module at '110-capturing-rules' was renamed but its content remained unchanged.
