| varnumbers/3 | Inverse of numbervars/3. |  |
| varnumbers_names/3 | If Term is a term with numbered and named variables using the reserved term '$VAR'(X), Copy is a copy of Term where each '$VAR'(X) is consistently replaced by a fresh variable and Bindings is a list X = Var, relating the X terms with the variable it is mapped to. |  |
