Thanks for the extra detail.
Is there a solid reason to ever use an interface over an
abstract class? (Other than multiple inheritance).
I'm such a noob at anything related to OO.
The general question is tricky, as different languages differ
in details what is forced and what is allowed for abstract
classes and interfaces.
But roughly speaking, my opinion is: if you can/want to provide
some default behavior than you are about to write an abstract
class.
If you are about to provide information/restriction of
behavior, then this is more like an interface.
Ok. What would go wrong (in D) if I just replaced every interface
with an abstract class?
