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.
