Effective code reuse is desirable, but difficult to achieve in
practice, since it is often necessary to adapt code before it can be
reused successfully. The good old solution to code reuse is simple:
copy, paste, then edit as needed. This is a brilliant idea, except
for the maintenance problems it causes. In this paper we introduce
a language extension for declaratively performing adaptive code
reuse at compile-time. We decompose reuse into two operations;
clone existing code, and adapt it to new requirements.
The clone and adapt technique allows flexible code reuse, untangled
from subtyping and other irrelevant features, and without the
maintenance nightmare of copy and paste programming.
