Interesting talk. Templates are indeed slow but the reason why
I use them over CTFE functions (or why i leave out ctfe in
general and just use functions) is that they don't require 20
GB of RAM for some medium-simple tasks (liked Pegged)
That can and is being fixed.
Templates can only be fixed partially and I am not even sure of
that.
Templates could be made faster but I don't really like losing a
feature or a possibility for it. imo D is very friendly and
easy to learn for newcomers, if a feature is slowing down
things a lot but making it a bit easier to learn/use, I would
prefer to keep that feature.
I am not suggesting to remove templates.
I just want to raise awareness that they have a rather high cost.
CTFE performance is fixable. Template performance might not.
