Currently, D supports:

3. C++ class field and vtbl[] layout
4. C++ function calling conventions
But what is missing is name mangling to match C++ templates.
This makes it awkward and tedious to construct a D interface to
a C++ template.
Andrei has proposed that D support, for templates declared
within an extern(C++) block, C++ name mangling. This should not
be difficult, it should not break any existing D source code,
and will enable limited interaction with C++ templates from D.
One nice side benefit is that no other language offers such
support, and given the increasing ubiquity of C++ template use,
it would give us a nice leg up.
Do different C++ compilers even mangle template names in the same
way? I remember function and classes mangling being almost
standard nowadays, does this apply to templates, too?
Sure this would add to the "Cool things you can do in D"; do you
have any estimate of the amount of work needed/target release?
