Further question - my internal data representation is a vector of
strings
Says posix only. But googling for it brought up System.IO.MMap, which
does seem to be cross-platform.

The vim autoindent for haskell is really bad :( Is there a better
indent.hs file floating around somewhere? Alternatively, is the emacs
haskell mode better enough that it's worth my time learning my way

Mythryl [http://mythryl.org/] is an ML dialect that mostly puts an
Algolish syntax and some good posix interoperability atop SML/NJ. More
