I like the one function.
There's also a basic difference. Write takes a string (or
strings with the proposal). Print took anything and called
str() or repr() to convert.
The difference between write and writeln is that the latter
puts in the return. Since it's on Guido's list, and since I
don't think it will cause compatibility problems, I suspect
that a patch to do it wouldn't be rejected out of hand. I'd
suggest making writeln (which is a new method) default
to inserting a single space, and leave write to default to
not inserting anything between the strings. (And remember
to do the doc update at the same time - the core developers
really like that.)

Reload doesn't work the way most people think
it does: if you've got any references to the old module,
they stay around. They aren't replaced.
It was a good idea, but the implementation simply
doesn't do what the idea promises.
