Bug 9767 – Confusing compiler error generated when names collide across modules.

If I create two modules which contain duplicate declarations.... a.d ===================== module a; import b; import std.stdio; void function() voidFun; struct foo { typeof( voidFun ) onCb; }; void myCb() { writefln("I've been called"); }; void main() { foo f = { &myCb }; usefoo(f); }; and b.d ========================= module b; void function() voidFun; struct foo { typeof(voidFun) onCb; }; void usefoo( foo f) { f.onCb(); }; ============================================== dmd produces following error message. dmd -I. -c -ofa.o a.d a.d(18): Error: function b.usefoo (foo f) is not callable using argument types (foo) a.d(18): Error: cannot implicitly convert expression (f) of type foo to foo scons: *** [a.o] Error 1 scons: building terminated because of errors. ================================================ Obviously pilot error on my part but I'd argue the error message could be made more helpful. Cheers, A.

Basically the same thing as Issue 9631. *** This issue has been marked as a duplicate of issue 9631 ***
