To answer your question, depends what you mean by clean. We can capture
the shared lines in a closure with lambda { ... }, or we can move them
to a function and call the function, but that's basically the extent of
the control flow power we have here. (Well, unless we want to start
using continuations!)
In the latest version of the code, the shared lines are now exactly the
same, and are simply duplicated. Maybe once a :prev branch is added a
refactor will be necessary.
