Supporting read() with fileinput?

I'm was wondering: would it be a good idea to have the FileInput class
support a read() method? I found myself running into a small problem
while using xml.sax.parse in combination with fileinput. Here's a
snippet that demonstrates the problem:
This doesn't work, because fileinput.input() isn't a file-like object:
it doesn't have read(), so it can't be converted into a nice InputSource.
But I thought it might be nice to have one, so I cooked up a quick
class to make it work:
def __init__(self, f):
self._buffer = 
self._f = f
def read(self, bytes):
if not self._buffer: self._prime()
next_block = self._buffer[:bytes]
And now I can get:
to work. But I'd rather make this solution a bit more permanent.
*grin* Would it be a good idea to add a read() method to FileInput to
make it more file-like?
