I have a strange bug I can't figure out dealing with re-providing a struct that
was contracted in my require.
Module A:
Firstly, I have a specific contract for my struct:
(provide/contract (struct mystruct ([field integer?])))
I have another part of A I will contract later:
(provide a)
I have several other modules that give a, b and c in module A different
contracts, but only slightly, so I have a macro for it in module A.
(define-syntax-rule (myprovide param)
(begin (provide/contract [a param])
(provide (struct-out mystruct))))
Module B:
[require module A]
(myprovide any/c)
ERROR:
struct-out: no binding for structure-type identifier at: mystruct in:
(struct-out mystruct)
This works if Module A just does (provide (struct-out mystruct)), but I don't
want that.
Is it really the case that I can't re-export this struct using struct-out, or
is there a bug in provide/contract?
