Although I know that NSInvocation was added (from Leopard?), I didn't use it

NSInvocation predates Mac OS X...
Oh. right. I forgot that.
Is there any benefit in using it? My guess is that an NSInvocation instance is used
repeatedly, but using the "selector" based method is not inconvenient for the
most of cases.
Is there any other benefit in using the NSInvocation?
NSInvocation is a very flexible class, and can be used for a wide variety of
tasks, but it is also (therefore) more cumbersome to setup and use for the
simpler things that you mention. It is not often used, so if you don't know
that you need it, you probably don't.

intention of creating of that was. Your last statement can't fulfill my
curiosity. :)
Thanks anyway to spare your time to answer my question.
