| * @assertion We say that a variable x is promotable via initialization given |
| * variable model VM if x is a local variable (not a formal parameter) and: |
| * |
| * VM = VariableModel(declared, promoted, tested, assigned, unassigned, |
| * captured) |
| * and captured is false |
| * and promoted is empty |
| * and x is declared with no explicit type and no initializer |
| * and assigned is false and unassigned is true |

| * @description Checks that if captured is true then promotion via |
| * initialization does not happen. |
