Yes, my immediate application is for unboxed arrays, but if I'm going to
learn the TH infrastructure, I might as well try to build a library 
that can be extended
to support different kinds of arrays.

I once wrote a compiler for a little language that controlled some 
network
hardware, so I have a soft spot for parsing ;-)

BTW, I have a patch that will build DecodeTH.hs under 6.2, using the 
new TH
syntax. It's quite simple and no doubt you could do it yourself in a 
few minutes, but
I can send it to you if you'd like.
