C++ function template partial specialization?

by

Function partial specialization is not yet allowed as per the standard. In the example, you are actually overloading & not specializing the max<T1,T2> function.
Its syntax should have looked somewhat like below, had it been allowed:

// Partial specialization is not allowed by the spec, though!
template <typename T> 
inline T const& max<T,T> (T const& a, T const& b)
{                  ^^^^^ <--- [supposed] specializing here
  return 10;
}

In the case of a function templates, only full specialization is allowed by the C++ standard, — excluding the compiler extensions!
