Unable to publish closed source library without workaround and ugly
PIMPL design.
Consider this:
----------- file s.d ------------
struct S {
int x;
this(int x) { this.x = x; }
int getX() { return x; }
}
----------- file s.di ------------
struct S {
this(int x);
int getX();
}

User code:
import s;
S s = S(3);
writeln(s.getX());
I doubt this reserves enough space on the stack for the copy.
Ta dah! Implementation is hidden, no PIMPL. Of course, inlining of the
member functions won't work, but it won't work in C++, either, when this
technique is used.
I.e. you can use .di/.d files just like you'd use .h/.cpp in C++. The
technique works with classes, too.
