Hm, have I ever said those are never used? x_X Quite the 
contrary, good chunk of discussion was about how this is 
foundation for implementing majority of std.meta

I still can do it without DIP63 (this is for example what vibe.d 
internal meta package uses) but I can't get myself into placing 
something like this in standard library, it feels too Boost. 
DIP63 does not change anything fundamentally about DIP54 but 
allows much more readable and maintainable implementation.
