I would assume that Bad Things would happen in that case, based on my understanding of how fast enumeration is implemented. It gathers and returns a C array of pointers to the values in the collection, which can then be enumerated with simple pointer arithmetic. Changing the original collection object would leave the C array out of sync with it, leading to Bad Things happening - maybe an exception, maybe a crash, I don't know, but definitely nothing good. sherm-- -- Cocoa programming in Perl: http://camelbones.sourceforge.net _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
