Comment (by tscrim):
I doubt it's worth it to cache it...
Anyways, the string representation would probably be something like this
(untested):
{{{
def _repr_(self):
w = max(len(str(v)) for row in self for v in row)
fstr = '{:>' + str(w) + '}' # should result in something like '{:>30}'
return '\n'.join('[' + ' '.join(fstr.format(v) for v in row) + ']' for
row in self)
}}}
