Templates with the same name as methods not legal?

[Simen Haugen]

If I try to call a template when a method with the same name exists I get a 
compiler error:

template isInteger(T)
{
 static if (is(T == int))
  const bool isInteger = true;
 else
  const bool isInteger = false;
}

class Test
{
 bool isInteger()
 {
  return isInteger!(int); // Yields an compiler error
 }
}

Gives me the error:
test.d(15): template instance isInteger is not a template declaration, it is 
a function

To me it seems this should be legal as my method doesn't take any template 
parameters and the compiler should understand that the template should be 
called.. There must be something I don't understand here...
