The following is a much simplified version of some code that is
refusing to compile. Is there anything technically wrong with the
code?

class ClassWithTemplateFunction
{
   public:
      template<class T> inline void SomeSillyFunction(T value) const
         {
         }
};

template <typename T> void TemplateFunction( ClassWithTemplateFunction
& rC, T value)
   {
   rC.SomeSillyFunction< T >( value );
   }

int main()
{
   ClassWithTemplateFunction C;

   int value = 0;

   TemplateFunction<int>(C, value);

   return 0;
}

The error I get from the compiler is " Parse error before '>' " on the
line: rC.SomeSillyFunction< T >( value );

Any help would be appreciated.

Try:

rC.template SomeSillyFunction< T >( value );

My fix is: rC.SomeSillyFunction( value );
This way the compiler is left to figure out how to instantiate the
template. Your fix is rather confusing? Why is adding 'template' here a
resolution? Can you make an analogy as an explanation?
