[Nix-dev] which is the best location for .hi files hardly ever used by useres ?

[Marc Weber]

My first attempt was just installing to $out/
After having installed about 100 packages I found some problems.
Some collisions and some missing C deps.

The collisions are caused by .hi files.

Do you agree that this would be a good place to put them:
$out/lib/XXXXXXX-ghc-v/XXXXXXXXXXXXXXx-name-v/ ?

Prefixing the compiler version helps not getting too much directories...
I've read that a system might get slower when having more than 5 to 7
thousends directories in one folder.
