Parse Go packages with ease

Behavior notes (v0.5.0+)

Newly supported types

• *types.Alias (Go 1.23+ gotypesalias=1) is resolved via types.Unalias. The alias name itself is not preserved (e.g. type UserID = string is parsed as string).
• *types.Signature (function types) falls back to Any{}.
• *types.TypeParam (generic type parameters) falls back to Any{}.
• Generic type aliases (Go 1.24+, e.g. type Vec[T any] = []T) are also handled via types.Unalias.

Migration from previous versions

• Inputs containing func(...) fields, generic type parameters, or type aliases used to panic with unsupported named type: *types.<Kind>. They now parse successfully and produce Any{} (or the resolved underlying type for aliases). If your downstream code relied on this panic for fail-fast validation, install a custom Replacer that explicitly rejects these kinds.
• The panic message wording changed from unsupported named type: to unsupported type: (the previous wording was misleading since Map, Slice, etc. are not named types).

Replacer caveat

• When a *types.Alias is encountered, the user-supplied Replacer is invoked twice — once on the original alias type, then again on the Unalias-resolved type via the recursive parseType call. Replacer implementations should be idempotent.
