Yep, just use the DefiniteIntegral functional

Actually, DefiniteIntegral is current limited to square-root singularity spaces. But it can be done via the following:
S=Chebyshev() Q=Integral(S) B=(Evaluation(S,1.)-Evaluation(S,-1.))*Q
We can leave this issue open until this becomes implemented as the default for DefiniteIntegral
A default DefiniteIntegral is now implemented.
