Hi all, Here's a simple patch to get rid of the following warning: Warning: at toplevel: assignment of value of type `(procedure print-call-chain (#!rest) (or pair null))' to toplevel variable `print-call-chain' does not match declared type `(procedure print-call-chain (#!optional (refine (output) port) fixnum * string) undefined)'
Alternatively, we could change the type to match the implementation, but then we should also document the fact that the call chain is returned. This doesn't make much sense to me. Cheers, Peter
