"string literals" do not have a type; they are, in some ways,
polysemous.  They are considered char[], wchar[], or dchar[] based on
where they're used.  If they're used in a situation where it could go
either way (such as this overloading case), it's an error.

The solution is simple: affix a 'c', 'w', or 'd' to the end of the
string literal to give it an explicit type.
