well, sort of -- it's pre-processed first, to add some numpy features, 
including parsing of NaN's. So it wouldn't be all that hard to add this 
too (well not that hard in the context of messing around in ugly C code, 
anyway).

See my messages about fromfile() a few weeks ago for details.

By the way, I got as far as identifying bugs/issues in that code, but 
not fixing them -- I'll try to do that before the upcoming 
1.5/2.0/whatever release.

If anyone wants to work in this issue, it might make sense to collaborate.
