Probably not as much as you think. :)

Absolutely agree. What I'm suggesting is writing such
functions (like obBone(objectname, bonename) you
talked about earlier) in a BPyDriver module and have
it autoimported in pydrivers, so people can use them
instead of doing the work themselves.

I would say any operation that uses the same
subexpression more than once is "complex". So, if you
want to have a mix between rot and loc for the same
bone (or something like that), it'd say it starts been
more complex (you'd have to end up fetching the same
bone twice, to make up the expression). Anything which
would require a ternary operator, same thing.
