Description

Is there a way to add signatures for methods in core classes added via refinements?

I remember there was an extends (or smth similar?) keyword for monkey patches, but that has since disappeared from the syntax page. Is there an alternative?

Research direction

Start with the syntax page and search the repository for existing references to refinements, monkey patches, and the former extends syntax. Determine whether RBS already supports signatures for refinement-added core methods; done should be a documented supported syntax or a clearly scoped implementation proposal.
