Comment(by vbraun):
I agree with you that compatibily should be preserved if possible.
But since the returned vertices/rays/... are now their own objects instead
of just lists of numbers any old code will break even if we return lists
instead of generators. On a more fundamental level, I think one should
always return generators instead of lists if possible (unless one is just
exposing some internal datastructure). That avoids unnecessary list
creation and enables parallelism. This is why I always favoured generators
over returning lists when I had the choice.
The alternative is to rewrite the code to always return lists instead of
generators. I don't think anyone is going to use vertex_generator() if one
can get a list out of the much shorter vertices() method.
