I think perhaps @exarkun's suggestion is perhaps sensible in this case.

I guess what I really wanted to suggest was experimenting with judicious use of `_` as lower precedence separator. The example I gave was one use I was familiar with. Prefixed method names are one that are specifically allowed by twisted's coding standard. There may (or may not) be others.

It seems to me that vertex is a good place for this kind of experiment, and I wanted to carve out an exception for it.
