fair enough. but, you can still provide for automatic conversion in cases where one wants to feed a lambda to libdispatch or some some cocoa/foundation class. As I said earlier in this thread...if you can make that happen, I'll be happy.

The goal that I'm lobbying for is to allow 3rd party mac developers to keep as much of their code in standard syntax and built upon standard libs as possible. Not only does it make the lives of existing mac developers easier, but it lowers the barrier to developers from other platforms to come to the mac.
