To simplify the algorithm, the tool could be made non-interactive.
Instead of prompting for when to refactor, the tool simply outputs a list
of all duplicate code snippets.
The list is sorted by the string length of its elements.
Then things not worth factoring out, like "0 >" appear at the end and can
be easily ignored.
This seems more straightforward than maintaining a list of things not worth
factoring out.
