Hi,
recently there is much talk about extending C++ interop in D but it is unclear
to me what that means. Functions and virtual class methods are already callable.
What else is planned in the near future? Exceptions? Support for C++ templates?
(that seems difficult no?).
Currently, D supports C++:
* function calling
* name mangling
* namespaces
* templates
* member functions
* single inheritance
* basic types that exist in C++ but not D (like 'long')
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.
