Comment(by mjo):
Almost! Would you mind moving the comment to its own line? There's nothing
wrong with it at the moment, but in-line comments like that are given
special treatment (e.g. #long, #optional, #todo...) so I think they should
be avoided to prevent unexpected interactions.
Also: I find regularity defined "for all vertices..." so it is vacuously
true that the empty graph is k-regular for any k.
I'm running a full ptestlong with the patch, and don't expect any
problems.
