Not true. Under OS X, retaining a block on the stack does nothing; -copy must be used. This is both the documented and observed behaviour. There are two reasons for this: 1) -retain is a no-op under garbage collection, but blocks still need to be copied to the heap; 2) it would violate the contract of -retain as per the NSObject protocol documentation. -- Jens Ayton _______________________________________________ Gnustep-dev mailing list Gnustep-dev@gnu.org https://lists.gnu.org/mailman/listinfo/gnustep-dev
