Since D uses the single inheritance model for classes, I wonder
if it is possible to write a class then extract the interface
from it?
e.g.,
class myclass
{
public void foo() { writeln("adf"); }
}
mixin!(extractInterface!(myclass, myinterface));
Where the mixin creates the interface as if I typed it by hand:
interface myinterface
{
void foo();
}
This would greatly simplify having to start writing from a base
interface then add the class. It would also let one do multiple
inheritance from classes that are already defined.
Since every class must have a well defined interface, this
seems like it should be possible and relatively easy using
reflection. A bad idea?
I guess the main issue here is that myclass would then need to be
specified as being derived from myinterface after it was
generated! Not sure if this is possible to solve in D?
