Hi John,

This looks fantastic and fun to play with.

A few issues:

* running DrIFT on src/E/TypeCheck.hs fails with an illegal
bytesequence in hGetContents. I'm guessing that this is only an issue
when building DrIFT with GHC 6.12+, and that the file contains bytes
illegal in UTF8. I deleted everything funny looking in the file and
then it went smooth

* The way you use sed doesn't work with the BSD sed that ships with my
Mac Book. Installing GNU sed and using it works. Similarly, BSD find
doesn't know about '-name', so make hl-clean results in sadness.

* jhci works great, but jhc crashes when I try to compile something:

jhc: <stdout>: hPutChar: invalid argument (Illegal byte sequence)

Again, this seems like the handle is in UTF8 mode and we're trying to
output something non-UTF8.

* cabal install has a --jhc flag, but it doesn't seem to work:
>>>>>

I have jhc installed in a non-standard location (under ${HOME}/usr) so
I may need to have some environment variables set up. This is wil
Cabal 1.8.0.4 and cabal-install 0.8.2

Keep up the good work!

I have an implementation for STRefs I threw together this afternoon
for jhc if you're interested. I can't test it properly, though, with
the compiler crash above.
