For the integer variable, it manages to resolve the overload.  Indeed, 
it calls the uint version.

However, with the literal, it doesn't, even if it has been cast.  This 
is absurd.  Just as integer variables don't implicitly convert to enums, 
neither should integer literals.  And that line 10 passes but line 12 
doesn't is even more absurd, as both have the same type set in the same 
amount of stone.
