I would like to export some functionality as external shared

Is it possible to do that in D Language
Yes, as long as the symbols you want to use externally are
`public`, which is the default.
When it comes to linking, the main factor is usually matching
symbol mangling. In C you would help users do this by
distributing your header files. In D it's more common to
distribute your source code, so if you want to distribute a
"header" you'll need to remove your function bodies:
```d
//regular function:
int add(int x, int y) nothrow{
x += y;
return x;
}
//for a D "header":
int add(int x) nothrow;
```
what are limitations?
The desired template instantiations must be generated at compile
time, not at link time. CTFE probably won't work.
Example of shared dynamic libraries depending on other shared
dynamic libraries would be great as well.
There should be no material difference to using a shared library
from an executable binary.
