Well, I have a patch series somewhere on my disk that adds ghc-toolchain
and hides ghc, similarly as gcc-toolchain.  Somehow, I think that, “guix
shell ghc-toolchain” should just work out-of-the-box.  And the
replacement of the C toolchain would be done with the package
transformation with-c-toolchain.

Bah, the series needs polishing…  arf!

Cheers,
