Description
Currently the function #set is marked as total (with functional attribute).
But it's not actually defined in the case where the key is in the Map, but the value associated with the key is not an Int.

Research direction
Locate the definition of #set and its functional attribute, then inspect the case where the key is present in the Map but its associated value is not an Int. Review the surrounding Map and Int semantics to determine the intended total behavior; done means #set is defined consistently for that case and its totality claim is correct.
