| documentation: |
--- Returns some value satisfying a predicate, i.e., some argument such that --- the predicate applied to the argument can be evaluated to `True` --- (currently, via an incomplete depth-first strategy). --- If there is no value satisfying the predicate, the computation fails. --- --- Note that this operation is not purely declarative since the ordering --- of the computed values depends on the ordering of the program rules. --- Thus, this operation should be used only if the --- predicate has a single solution. |
