What would be the right place to put a check on restriction arguments.

For instance, this

    from ufl import *
    V = FiniteElement("CG", "triangle", 1)
    v = TestFunction(V)
    a = v(' +')*dS

gives:

    Couldn't map 'v_{-2}' to a float, returning ufl object without 
evaluation.

which is a rather confusing message for newbies.
