I have a project with 57 prefab structure types. I need to construct instances using a local contract (module level contracts do not fit my needs here). Since I cannot define guards, the solution is easy enough.
(struct foo (num) #:prefab) (define/contract make-foo (-> real? foo?) foo) Problem: I already have a few hundred constructor calls without contracts. I could either A) rewrite them all to use contracted constructors, or B) attach local contracts in a sweet spot so that I don't have to rewrite anything else. I prefer option B, but it doesn't look like I can attach a local contract to a constructor with `struct` alone, or even with an impersonator. When I hack around to rebind or hide the constructor's identifier, I break compatibility with `match` and `defstruct*`. If you were in my position, what would you do? -- ~slg -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
