Comment (by vdelecroix):

 Hi,

 Actually it was good to have another look at the code since I introduced a
 bug for weighted digraph.... (see the test in the last commit that will
 appear in a second).

 @dcoudert: actually `is not` is an operator that should be as fast as
 `is`. While `not` involves some function call... it is strange that you
 get those timings.

 Vincent
