And it's just so *convenient* to use it.

But even a simple, single-pass word-counting using the standard IO is
slow, it would be really nice to write this in a straightforward way
and still get decent performance.

As somebody just said, you get to chose between speed and
simplicity/clarity of code.  I would like both.

Couldn't readFile et al. provide the standard interface, but use
hGetBuf tricks (e.g. from your 'wc' entry) behind the curtains?

If I haven't seen further, it is by standing in the footprints of giants
