FixedPoint - applies a procedure repeatedly until the result is an invariant
any proc FixedPoint -> any
any proc integer FixedPoint -> any
(kaeschperle) {Rest (_) join} FixedPoint --> (___________)
(kaeschperle) {Rest (_) join} 1 FixedPoint --> (aeschperle_)
(kaeschperle) {Rest (_) join} 3 FixedPoint --> (schperle___)
FixedPoint called with three arguments applies the procedure not more
than n times. The first argument is the initial value.
Compared to Mathematica the first two arguments are reversed
for better conformance with RPN.
