[Haskell-cafe] Compiling GHC 6.8.3 on OS X with readline support

Well, yes, see the GHCi wiki for how to augment 'rlwrap ghci' with
some basic completion support (filenames, flags, module names):

http://www.haskell.org/haskellwiki/GHC/GHCi#rlwrap_-_what_to_try_when_your_GHCi_was_compiled_without_readline.2Feditline

but is there a way to make rlwrap's completion context-sensitive?

As with bash's complete command, for instance, I'd like to be able
to tell rlwrap that :load wants filenames, while :module wants module
names, and :set wants settable things. If your ghci is readline/editline
enabled, you get quite specific support (or so I gather from the
source code..), while rlwrap seems to throw everything in one pot.

That said, rlwrap is still a good workaround,
