tl;dw: there's precedent.  Historically typeinfo has been 
overused in the runtime library (I think it's because a lot of 
the code/architecture predates today's templates).  For example, 
if you compared an int[] to an int[], the compiler would generate 
a function that looked up a comparator for int using RTTI, and 
would iterate over the arrays calling it on each element.  That 
video is about replacing code like that with smarter templated 
code that's not only faster but results in *less* code bloat.
