To multiply apply a function, I'm currently using:
multiplyApply f n a = (iterate f a) !! n
...is there a Prelude function I've missed that already does this?
Unfortunately not.
Could I be doing this better?
I think an explicit recursion would make it easier to compile efficiently, and it can give a better error message for n < 0. -- __("< Marcin Kowalczyk * qrczak@knm.org.pl http://qrczak.ids.net.pl/ \__/ ^^ SYGNATURA ZASTÊPCZA QRCZAK
