No, I re-read what you wrote, and now I understand what you mean by
typical values.  I think this could be useful. The difficulty
is that the conditions can become extremely elaborately nested as the
computation continues, and so there is a need for simplification.
For example, if the answer is stated as 3 different forms for x>0, x=0,
and x<0, but  the forms are equal for x>0 and x<0, then the simplifier
should make two forms, one for x=0 and one for x#0.

(I do not expect that the CL condition system will help, unfortunately).
