Not really sure what you mean, but you don't need to use 
templates for this. You can just pass the parameters in through 
the function parameters instead. No template bloat.

Assuming you want to know the values of those variables at the 
call site then that would be bad anyways. As now every function 
would have to pass this extra meta data. The function name, line 
of code, name of the module, basically all of it will need to be 
stored in this hidden struct and passed even when it might never 
even be used. Otherwise it would just complicate when you do or 
don't need to pass the struct. It's better as it is now, you only 
pay for it when you need it.
