fixedpoint and scan-fixedpoint are adverbs that apply a monadic function to a given noun y until it stops changing, or the initial value has been repeated.
Fixedpoint(/) produces a single value, the final value.
Scan-fixedpoint(\) produces a list of all intermediate values. It is often useful for debugging fixedpoint.
