| Summary | 0002040: assumes clause and labels |
| Description | My understanding of assumes clauses is that they refer to the pre-state of a function.
The attached example, however, works differently.
The function push_back has two disjoint behaviors that rely on the predicate "full".
The function push_back_twice is only verified if I add the label "Pre"
to the predicate "full" in the assumes clauses of function push_back.
I think this is a bug.
It should not be necessary to add this explicit label. |

I remember that Kim Völlinger had observed the same(?) problem in Oxygen and
that it was fixed in Fluorine. |
