I'm coming around to this actually -- not because it's easier to grok than:

data = open('some_file').read()

but because it could be an atomic operation, and close the file properly.
and Is easier to grok than:

with open('some_file') as infile:
    data = infile.read()

and heck, it would even keep the door open to being made a built-in in the
future.

Maybe it's time to hear from the OP on this one -- after all, most of us in
the discussion are already really familiar with the options!
