i have a question about a polynomial ring over a polynomial ring. suppose 
i have

R1.<w> = QQ['w']
R2.<z> = R1['z']

and i construct some sort of element,

f = z*w

i know that if i want to evaluate z, i can do something like

f(1)   # output: w

and even

f(1)(5)   # same as w(5)

. the question is: how do i evaluate w while leaving z untouched?
(i actually want to do this when R1 is a multivariable ring, but i imagine 
it works the same way.)

thanks,
kyle
