Raising value to positive power is quite common operation yet ^ operator generally couldn't be used because it leads to warning about type defaulting (rightfully) and one wants to keep code warning free. Actually it's problem with warnings and I don't think adding some ad-hoc rules for generating warning is necessarily bad idea

You can disable the warning with -fno-warn-type-defaults.

Bu in most of the cases I do want this warnings. It's possible to get something default to Integer when it should be Int. There are only few cases when it's not appropriate. Only ^ and ^^ with literals I think
