Yep, looks like the winner. I should've inferred from the fact that "unbound identifier" is a compile time error that there must be a way to check said binding at compile time, sigh. Also, I only learnt that its a compile time error today and couldn't quite figure how the expander can be certain. Now I'm thinking, wait, all those syntax objects have sets of scopes attached for a reason. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
