Extended Dependency Generation Proposal

[David Eichmann]

Hello GHC Developers,


I've recently been working on a proposal (found here 
<https://github.com/ghc-proposals/ghc-proposals/pull/245>[1]) for 
"Extended Dependency Generation". This new feature takes the form of a 
new build option/mode that outputs comprehensive build dependencies for 
building Haskell modules. This allows external build tools, such as 
cabal-install, to implement correct incremental builds with 
recompilation avoidance using GHC's one shot mode to compile individual 
modules.

All input is appreciated. It would be particularly helpful to hear from 
the Cabal, Stack, and Shake communities.


Looking forward to hearing your comments,

David Eichmann
