Thanks for your help, but I just found out it works for me to replace
all of the braces with curly ones and then do the comparisons, and that
works. Now, however, it seems that isCaseInsensitiveLike: goes into an
infinite loop sometimes. Its really confusing, because its never on the
same string (these are NSMutableStrings I am comparing, by the way, that
are from three to twenty characters long). Is this a common mistake that
I am making? Or is this something that is just a bug and I should go
with the other frameworks (I would prefer to not use any non-apple
frameworks, but if I must, I must...)
