Wait, what? Doesn't D specifically _not_ have SFINAE? You can
use static if to test what compiles, and the branch whose
condition compiles is then the on that gets compiled in, which
kind of emulates what you'd get with SFINAE, but that's not
really the same as SFINAE, which just outright picks the the
template specialization which happens to compile while letting
the others that don't compile not generate errors. D complains
when you have multiple, matching templates. So, what do you
mean that D has SFINAE?

If a template does trigger a static assert,
that static assert is ignored if there is another template in the
overload set that could match.
