| Summary | 0001291: Typing rejects polymorphic logic constants |
| Description |
The followingACSL declaration should be valid
axiomatic Bag {
type bag<X>;
logic bag<X> empty<X>;
}
but is rejected by typing :
[kernel] user error: some type variable appears only in the return type. All type variables need to occur also in the parameters types. in annotation.

| Additional Information |
I know it is annoying to implement since it requires a full-fledged type inference algorithm. But I don't see any way to avoid it... |
