[arch-general] Why ghc 7.2.2 ?

[Bernardo Barros]

OK!

I agree with what is on the first e-mail from [arch-haskell].

Vesa idea is quite good. I quote here:

My question was about the ghc version 7.2.2 instead of 7.0.3. The
reason Haskell Platform did not 'upgrade' it is because it is a
"technology preview' release as you can read in announcement:

> The 7.2 branch is intended to be more of a "technology preview" than
> normal GHC stable branches; in particular, it supports a
> significantly improved version of DPH, as well as new features such
> as compiler plugins and "safe Haskell". The design of these new
> features may evolve as we get more experience with them.

And I wonder if would be better to wait until the next "production"
release to upgrade ghc in [extra]
