Inconsistent behavior with pi()

[Mats Rostedt]

If I type pi() it is ok but e.g. sqrt(pi()) gives unknown function (sqrt(pi) works). I think you had to use pi() and not only pi some versions back.

It would probably be better if pi() did not work at all.

Btw, I really like SpeedCrunch.

This is not limited to pi, it happens with any constants or user variables, so this is most likely an issue inside the evaluator.
