Return node/edge reference on add?

[nernst]

I'm just starting with pygraphviz, but it looks like if I add a node:
G.add_node('hi')
the method doesn't return a reference to the new node. If I want to
manipulate it, I need to do
n = G.get_node('hi')
which I can then manipulate to alter attributes, etc. I realize this
is possible if I pass the attribute in to the args to add_node, but
this seems less readable.

Is it possible to return the reference in the add_node method?

That is certainly possible. And I don't see any reason why we shouldn't.
We would probably want to do the same for add_edge() then too.
