If I require base >= 7.9, does that get thrown out to work with GHC 7.4? How does that work?

So... to declare that I am using a new language construct, I place a bound on base.

I'm sure this makes sense to someone, somewhere....

Let's please step back, 1) I said we'd need a LANGUAGE pragma in response to hvr 2) A question was asked about enabling it by default 3) hvr said this would need a way of letting cabal know not to build it 4) I said it could be signaled with a bound on base 5) You said this assumed everyone had the latest GHC Your response was a non sequitur. As it happens, if you have code that hits a bug in GHC, then a pretty effective way of ensuring that cabal-install doesn't try to build it with an older GHC is to put a lower bound on base. I'm sorry if that is offensive. Anthony
