While that's definitely convenient (if you have C++11 variadic 
templates, anyway), I suspect that sort of construct would create quite 
a bit of code bloat.  (Permutational expansion depending on number and 
type of parameters.)

The compiler *might* be smart enough to save you from most of it via 
inlining, but I'm not sure how far I'd trust that.
