This is awesome. One of the things I've found while learning Haskell was that the connection between traditional editors (vim) and GHC is tough to reconcile. This seems like a great way to have all of that functionality in a turn-key package.
@tacticalgrace Do you have any plans to bring in GHC 7.10? And to add network connectivity?
@k1ix We will track GHC and LTS releases, but with an eye on stability. The GHC 7.10 line has been somewhat problematic with respect to regressions; hence, I didn't want to use it for the HfM launch.
Network support will come. (Given the nature of the product, I wanted to be conservative with sandbox entitlements for the first Mac App Store release.)
