In C and C++, ^ is a binary operator. Block objects would look like a unary ^, so there is no ambiguity. Note that C++ allows overloading of almost everything, including binary ^, but it doesn't allow creation of new operators like unary ^. -- Greg Parker gpar...@apple.com Runtime Wrangler _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
