Compiler should catch missing function name

[janicedatawire]

I have the following class defined:

    class Conversion {
       float answer;
       float Convert ( Unit input, Unit output){
          float answer = input.value.__mul__((input.baseValue.__mul__(output.baseValue)));
          return answer;
       } 
    }
}

I accidentally used foo=conversion(meters,feet) instead of foo=conversion.Convert(meters,feet) when referencing it. The compiler should catch this and complain.
