Do you know why we use name instead of mangled_name

Do you know why we use name instead of mangled_name

@celinval do we have available mangled name for StaticDef? The name and path are sufficient to get the correct variable.

error[E0599]: no method named `mangled_name` found for struct `StaticDef` in the current scope

You should invoke mangled_name in the instance, not in the StaticDef.

Thanks for fixing this.

I would mention a "Closes" for the original issue that this addresses.

Hey @feliperodri, can you please make sure this code works if the contract is added to a generic function? I don't know if we already have a test for that.

I added a comment to clarify why we can't use now mangled_name. I also reported the issue on CBMC (see diffblue/cbmc#8225).

I added a test with generics and recursion. I didn't find any tests like that in our regression.
