Tail-call optimization, probably. If the last thing a function does is call another function, the optimizer will change the final subroutine call plus return into a jump. The downside is that the first function will no longer have an active stack frame so it won’t show up in backtraces, unless there is a symbol file available. —Jens _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
