is it recommended to use @try .. @catch blocks as flow control like
it is used in Python. They say explicitly to use it rather than do a

fails.
Apple's stance on exceptions so far has been that, with the exception
of some proxy objects (e.g. Distributed Objects), they should be used
in Cocoa for programming errors only. Otherwise, you're supposed to
return a BOOL, or an NSError, e.g. via a reference parameter, if more
detailed failure info is needed.
Whether I consider that good or bad, it's what Apple recommend.
