Hi Paul,

Thanks for updating GEP-19 and #2933. Structural pattern matching in switch is a strong Groovy 7 candidate, and having a re-ported reference implementation on current master makes the feature boundary and performance discussion concrete.

I will read the updated GEP and the PR more carefully and leave comments there (especially around exhaustiveness, interaction with existing switch/isCase, and static compilation). Happy to help review as it lands.

Cheers,
Daniel Sun
