Comment (by alanz):

 Phab:D639 refers, which does not close this ticket, but is just the first
 step toward it.

 I strongly believe I am not introducing new bugs as it is a simple
 addition to rnMatch' with pure code that only sets a variable that is
 ignored in the rest of the compilation process, being introduced
 specifically for API Annotations.

 In terms of motivation, the current HaRe model is to do analysis on the
 RenamedSource, then transform the ParsedSource. Having funcction id
 locations available in all Match variants is vital.
