Yeah, I remember NSBlock from ObjC programming back in the day. Then blocks started showing up on other platforms due to Clang providing them. For example, Asterisk PBX software uses them to tame their memory leaks. Asterisk used to leak like a sieve. Asterisk only builds with Clang because of them. Jeff
