Sorry, I cannot make heads or tails out of your babble, but as it seems 
you are fascinated by templates and not really comprehending them, here 
are some general remarks about them which might be helpful.

I know this can be confusing, but in C++ it is actually pretty simple: 
templates are a compile-time feature. If you need something to be solved 
by template mechanisms, it must be known at compile time. And vice 
versa, if something is only known only at run-time, you have to do it in 
an old-fashioned run-time way - an if, a switch, etc.
