I did try to see if I could get that to work, but I couldn't figure it
out. I'll see if I can play around more with that api.
So say I did investigate a little more to see how much work it would
take to adapt the re module to accept an iterator (while leaving the
current string api as another code

If your intent is for the expression to traverse multiple lines (and
possibly match *across* multiple lines,) then, as far as I know, you
have no choice but to load the whole file into memory.

Is it not possible to wrap your loop below within a loop doing
file.read([size]) (or readline() or readlines([size]),
reading the file a chunk at a time then running your re on a per-chunk
basis?

Ack, typo. What I meant was this:
cat a b c > blah
>>> import re
>>> for m in re.finditer('\w+', file('blah')):
... print m.group()
...
Traceback (most recent call last):
File "", line 1, in ?
TypeError: buffer object expected
Of course, this works fine, but it loads the file completely into
m
The following example loads the file into memory only one line at a
time, so it should suit your purposes:
>>> data = file( "important.dat" , "w" )
>>> data.write("this\nis\nimportant\ndata")
>>> data.close()
now read it
>>> import re
>>> data = file( "important.dat" , "r" )
>>> line = data.
