Subject: [PATCH] Using compiled regular expressions for DACA2 functions
 (#1209)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

​The method “match” was used as a module-level function in ​for loops
of implementations for DACA2 functions so far.
Use ​compiled regular expression objects instead.

Delete a duplicate element from an alternation.
