| documentation: |
--- Gets one value of an expression. Returns `Nothing` if the search space --- is finitely failed. --- Conceptually, the value is computed on a copy of the expression, --- i.e., the evaluation of the expression does not share any results. --- In PAKCS, the evaluation suspends as long as the expression --- contains unbound variables or the computed --- value contains unbound variables. |
