Comment (by SimonKing):
Replying to [comment:234 tscrim]:
>> @Simon, I don't think that will work because python should run the copy
before passing to the lazy string, since I think the string's formatting
is the only thing being lazily done.
That's why I said "Why not use ''some kind of'' lazy string" in
comment:228. It would of course be a new class, along the lines of
{{{
#!python
class CopyOnPrint:
def __init__(self, x):
self.x = x
def __repr__(self):
return repr(self.x.__copy__())
}}}
