It seems to me that (set-implements? (mutable-set) 'set-add) should return #f, and in 6.1.1 (and I think 6.2), that's true.
But in the latest snapshots, it produces #t. It seems like it's implemented as an error message instead of not implemented at all, and `set-implements?` can't tell the difference between implemented with an error message and actually implemented. Is this a choice with reasons behind it, or should this be a bug? -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
