I copy-pasted the latest code and made some small adjustments.

In Xcode 26, if this is missing, a warning will appear at build time in the consuming package.

Adding it doesn’t resolve the issue, so I’m reverting it.

SwiftSyntax 601 introduced support for SE-0452 (Integer Generic Parameters), which changed the type of
GenericArgumentSyntax.argumentfromTypeSyntaxtoGenericArgumentSyntax.Argument.As a result, the test code could no longer be built with SwiftSyntax 601.
Since
GenericArgumentSyntax.Argumentcan be converted toTypeSyntaxusing.as(TypeSyntax.self), I’ve introduced a compatibility accessor namedargumentCompat600to maintain support for SwiftSyntax 600 and earlier.Note: This change does not implement support for Integer Generic Parameters itself.
