:-) Actually, you'll like it even more when you realize that
the "so called" cumbersome notation
f(w0=w[0],w1=w[1],...)
isn't. In fact, if d is any dictionary, if you do f(**d),
its as if you called f with the a bunch of key=value
inputs. So with the notation I propose you can
do arbitrarily complicated things like you suggest
just by doing f(**some dict). So what you want should
be easy to build on what propose. Thoughts?
