Can you actually reply to me instead of saying "read/watch
this"? I'm not going to watch an hour, just to see how you
going to achieve this.
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.
