Comment (by dcoudert):
I agree that we should try to let the code as readable as possible,
especially for non critical code.
If we want to optimize further, there is apparently a small difference
between {{{x is not None}}} and {{{not x is None}}} ;-)
{{{
sage: x = None
sage: %timeit if x is not None: pass
10000000 loops, best of 3: 57.8 ns per loop
sage: %timeit if not x is None: pass
10000000 loops, best of 3: 57.2 ns per loop
}}}
