What can be done with sets:

2*RR 	ok
RR/RR	=1
RR/(1+RR) => t/(1+t) ok

P=[1,2,3]
P/(1+P) = [1/2, 2/3, 3/4] =>ok

P=[1,2,3]
Q=[2,4,6]
PQ = PxQ = [(1,2), (1,4), (1,6), (2,2), (2,4), (3,6), (3,2), (3,4), (3,6)]

So Set Expressions are Rvalues

p in [1,2,3]
t in RR 

then a point can always be evaluated
z = p*t
z = p+t

but we need set expressions to draw lines:
L = exp(2*i*pi*UI)
P = [1,2,3]

Lines are one dimensional, so we only allow ONE set variable per expression
