Re: PROPOSAL: Restrict the type of (^), (^^), and add genericPower, genericPower'

I thought of two more reasons I'm against this proposal: 2) It isn't backwards compatible. It will cause some existing Haskell code to not compile. 3) It makes things more difficult in GHCI. Under this proposal, you'd have the following: Prelude> let x = 2 Prelude> 6 ^ x <interactive>: Couldn't match expected type `Int' against inferred type `Integer' On 11/17/07, Henning Thielemann wrote:

Let me guess - you don't use -Wall. :-) Warnings are not the problem, warnings point to a problem. The problem here is, that the compiler has to guess a type, because it cannot be infered from other operands.

I don't see how that's a problem. Have you ever had a case where defaulting to Integer produced the wrong behavior?
