I was thinking about the overload resolution functions suggested a while back by Arturo Cuebas[1] and had no idea why the compiler needs to be told the number of parameters in the first place. So I took his code and removed the numbers from functions, and it worked (in gcc). I guess that it didn't work for him because of his compiler. Well, it almost worked. Sometimes there is more than the one function that fits the template parameters. So I kept the numbered overloads to be able to match them. It might be possible to get these to work without the number of parameters by making the compiler prefer overloads for functions with less parameters. I've attached a demo.
