 I think conditional templates obviate most, if not all, of the need for

Which is it? Most or all? If it's not all, what's missing?


 There need to be some more steps taken, most importantly 
 unification of regular functions with template functions.


Why would having or not having that change the need for SFINAE?

I don't know; we haven't thought all of that through.

I've never seen any D code which used SFINAE. Why not simply disable it, 
  see if anything breaks, and _then_ look for alternatives for anything 
which actually requires it?
I strongly suspect that SFINAE is an obselete coding style in D. There's 
a decent chance that nobody is using it.
