Currently, D supports C++:

Note that there are no plans to support C++ semantics - the D
side
will support only D semantic rules. SFINAE, Koenig lookup,
etc., have
no place in D.
C++ interop will require the user to be flexible on both the
C++ and D
side, and bluntly will require strong knowledge of D and C++
and how
they work under the hood to be successful with it.
Probably the most tricky thing we're working on is interop
with C++
exceptions.
Essentially, we're going to see how far we can push interop.
To clarify, templates have to be instantiated on the C++ side
before
being passed to D, right? Is it correct that D can't
instantiate a C++
template?
Correct. Here's the syntax on the C++ side:

Understood, makes sense.
