As far as I can tell, the enabled state of specific segments of an
NSSegmentedControl (which you can set / get through

Pre garbage collection, this was straightforward: as long as you

I can see how this might be "exceedingly important" for deeply
recursive functions, but for the

But it's not the inner pointers I would expect to keep the object
alive -- it's the fact that

You can use NSPredicate for regexp matching, though no substitution

It's for a method called returnUIForFont:, not returnUIColorForFont:.
