Comment (by thomie):

 > I, for example, use makefiles during development instead of cabal
 because it allows for a faster code/compile/fix type errors cycle.

 Just curious: wouldn't `cabal repl` be faster? Or adding `ghc-options:
 -O0` to your `.cabal` file?

 If you want to proceed with the scanning the filesystem plan, I think it
 is best create a small wiki page, with a specification. See
 https://ghc.haskell.org/trac/ghc/wiki/WorkingConventions/AddingFeatures.
 Basically copy what you wrote in comment:15 + clarifications from later
 comments. That way it is easier to digest for others, so they don't have
 to read through all these comments.

 Paste a link here, and send it to glasgow-haskell-users at haskell.org,
 requesting feedback. Hammering the file system might be frowned upon by
 some, so make sure you explain the flag (name to be decided by you) is off
 by default. In case you don't get any reactions, go to #ghc on the
 freenode irc channel, and ask bgamari (ghc maintainer) if he thinks it is
 ok to implement this. Then do it and submit a patch.
