Overview

This is a bit magic… We substitute backreferences with PLACEHOLDERS. These are then, later, replaced by the appropriate value. (See BackReferenceReplacer) The simplest example is /(a) 1/ - So, we temporarily treat the “result” of /1/ as being “BACKREF-PLACEHOLDER-1”. It later gets updated.
