Hmm, I would think it would be possible to require files which are not
byte-compiled.  The reason that the language files (aside from
emacs-lisp) are not compiled by default is that they often have exotic
requirements which will not be present on most users systems.

Thanks for bringing this up, it looks like ob-haskell has fallen victim
to bit-rot.  I've done a fairly thorough cleanup of the file (just
pushed up the commit).  Please give it a test run and let me know
if/where I missed issues.

Yes, the language-specific files have not been manicured for clean
byte-compilation.  This is certainly something that should happen, but
probably not in the near term.
