Has anyone yet volunteered to do the hard work of defining an ADT and
made a proposal for how it should interact w/ the System.IO functions?

I think that lacking a FilePath module is a serious problem that is
holding haskell back.  Lots of languages use String for filepath, like
Python, which is hugely popular for these uses, but has nothing on
Haskell, IMO, except this single library.  

Lots of people have written home-grown FilePath modules.  How long can
we wait for an implementation to appear?
