I'd think you'd be commenting on the "Issue 5710" thread then, as 
that very much does affect the metaprogramming capabilities of D. 
I do agree that this is an area where D shines and where D can 
show off the most compared to its competitors.

You're probably right, but the people implementing this in D are 
already doing or have done it, so that's a good thing. Also, as 
someone who will likely only use the betterC subset of D, having 
some better primitives than printf in BetterC is a small boon, 
though I'd rather have something more like the new C++ fmt 
library than like printf.
