So there was actually a bug in the original refactor that didn't get caught by the spec suite, despite its huge expansion. I added some missing test cases in #12804 (also first commit in this branch). |

Why not make this one private too? Also, wouldn't it make sense to change its name, and avoid the renaming of arguments?

Yeah, I think private should work. I think the nodoc is an artifact from an earlier setup where private wouldn't have worked.
Changing the name would make this not be a constructor which causes problems with ivar initialization.

This patch extracts code that relates directly to implementation details of the libpcre backend from
RegexandRegex::MatchDataand puts it into a moduleRegex::PCRE.This abstraction is then to be used for an alternative engine using PCRE2 (#12790).
The first two commits are an separate change submitted in #12810.Commit
three and fourone and two are general refactors which are useful on their own and make the extraction easier.
