Re: Proposal: Add Data.Semigroup to base, as a superclass of Monoid

I'm against adding Semigroup to Base as it only has one useful operation in the class and no useful generic functions (without adding more overhead to Base - non-empty lists, naturals...). The most useful function from Semigroups for me is `times1p` (or its monoidal variant `timesN`). What about adding a function similar to `timesN` (perhaps with another name) to Prelude (and implement `(^)` with it)?
