Consider templating to be like the macro pre-processor, which expands #defines before the compiler gets to see them.

The compiler will "expand" your template parameters and then look at your function declarations. So, template parameter == function parameter. If you declare the same function twice, you will get an error.

You ask about return type. That is part of the function's 'signature'. Two functions with the same parameters but different return types are two different functions.
