It's not the first time I've seen this, and I still do not understand 
what the belief of template meta-programming causing bloat is based on.

It certainly increases compilation time, of course, since the point is 
to create a domain specific language for the problem domain -- using the 
type system -- and evaluate it at compile-time to generate the best 
targeted code, but it certainly doesn't make the executable needlessly 
grow at all.
All information about types is lost once a program is compiled. (apart 
from debugging information, of course)

RTTI is only emitted for polymorphic types, or when using explicitly 
typeid(a_type).
