[plt-scheme] mutual recursion in contracts

> And there is one. flat-murec-contract.

Oops, missed that. But it still requires that at the time of using 
flat-murec-contract I know all of the forms that might be mutually 
recursive. If I want to be able to have multiple expressions that use 
my macro and that are mutually recursive, I can't use a construct like 
that.

If I were only working with flat-contracts and/or predicates, I could 
use eta-expansion (in conjunction with flat-contract-predicate), so the 
contract expressions could be immediately evaluated, but wouldn't 
actually be used until they had all been defined.

But with h.o. contracts I don't know of a solution.

Thanks,
Dave
