support nix-shell develop-mode.

is it feasible to get nix-shell develop-mode environment?
so [nix-shell --pure --run 'cabal repl'] can be used for develop.

it's space-waste to use different tool for development and build.

I think that should work.

I haven't tried it for static-haskell-nix specifically, but in other nix+Haskell projects I regularly go into the nix-shell and do Cabal actions using runghc Setup.hs mycommand ..., e.g. the repl you mention.

Give it a shot and report back :)

i can use cabal for developing easily with static build.
only with emacs + dante, it will work.
but i have no idea how to do it for stack, i'll explore the stack2nix a little.

some simple example

i found haskell.nix is more friendly integrated with stack for nix.
