Comment (by tscrim):
The `has_key` is being deprecated (removed?) in python3 in favor of the
`in` syntax (which I believe is faster...?). Also I agree with Darij since
this loop is so small, I'd pull the `side == "right"` statement outside
as:
{{{
if side == "right":
for y in g:
r = y*x.inverse()
if x.length() < y.length() and r in ref:
d[x][y] = r
else:
for y in g:
r = x.inverse()*y
if x.length() < y.length() and r in ref:
d[x][y] = r
}}}
