There was a side discussion about how the `extern(C++)`
interface affects dmd-as-a-library.
Personally, my number-one complaint with dmd-as-a-library is
that I am forced to use `extern(C++)` when creating my own
`Visitor` classes.
In [`dmdtags`][1], this requirement has made it necessary for
me to implement my own C++-compatible [`Span`][2] and
[`Appender`][3] types, just to avoid the C++ mangling errors
caused by D's built-in `T[]` slices.
I have no use for overriding AST nodes, but the ability to use
`extern(D)` visitors with dmd-as-a-library would be a welcome
improvement.

I have already brought that up to one of our work group meetings
regarding dmd as a library as I have stumbled upon this also. We
have a solution for this, I'm going to try to implement it this
week.
