Move interactive-haskell functions from haskell.el

[gracjan]

Move interactive-haskell related functions from haskell.el to haskell-interactive-mode.el.

This is not quite straightforward. There are 5 other modules between haskell and haskell-interactive-mode in the dependency tree, and the functions that should move depend on 4 of them.
I can think of a few options (below). Would one of these satisfy?

• make a new module, haskell-interactive-commands, sitting above haskell-repl and friends, below haskell.el, with these functions (easy)
• move functions as far down the tree as possible, without new modules or changing the dependencies between them (merely tedious)
• document the purpose of each module, refactor code to match (much more work)

[gracjan]

Lets do option 1 haskell-interactive-commands as you described. If there is an easy and obvious way to move some functions down the hierarchy then occasionally do option 2.

Option 3 is too much work and in the light of coming Haskell IDE Engine it does not make much sense right now.

@bergey, were you able to push this forward?
