Now there is still the question whether the `extern(C)` code
will work as expected or not.
So with few patches could we make it work? DMD can write the C++
function prototype (as it does it with `extern (C)`) and then

`extern(C++)` functions use C++ name mangling, which includes
the types of the parameters in the mangled name. However, since
C++ does not have a built-in slice type like D's `T[]`, there
is no valid C++ mangling for a D

There is a syntax disagreement here that's why the D compiler
is instantly stopping you from doing any symbol generated
interaction with string in C++ interop. C++ doesn't know
'string' and C++ mangles with

So C-strings are just an array of characters that are governed
by simple functions and D strings also defined the same. So you
could see that D strings are possibly built on the architecture
of C strings. In

We can just assume what you're doing on the C++-side. Are you
using std::string?
You could try as a pointer + length and it might work, but
without seeing your complete code it's quite hard to know what
you want to do.

I was wondering why C++ linkage forbids strings as arguments

With C linkage, it's translated to a template that's defined in
the automatically generated header, but it just doesn't compile
in C++.

But dub pulls in so much stuff. Too much for me.
I like things which are clean,lean,little,small.
But when i use dub it links with so many libraries.
Are they really needed ?
