Hi Evan,

from an interface standpoint of view, I would prefer that optional
arguments were using key=value syntax, this will make it possible
to have other optional arguments added without using the


syntax when not setting


at the same time

yes I know that interface is not consistant ... especially in the
graph area we have 'both' but alas, that is what we get from being
backward compatible ...
