documentation:
|
Selects (indeterministically) some value in a multiset of values and returns the selected value. Thus, `selectValue` has always at most one value, i.e., it is a deterministic operation. It fails if the value set is empty. **NOTE:** The usage of this operation is only safe (i.e., does not destroy completeness) if all values in the argument set are identical. |
