Really? http://trac.sagemath.org/ticket/18785#comment:5 :-)
And it is all over the place in the twograph business...

it, but that did not stop me from accepting code that other thought
useful. Also, you add long lines of code to an already very very heavy
constructor, while you could turn it into an adjacency matrix with a one-
liner.. But that would result in possibly misleading error messages.
OK, OK, I just was learning from your approach to ticket
writing/abandoning ;-)
