Although the English module can provide aliases like $PREMATCH, $MATCH, and $POSTMATCH, the documentation warns to use -no-match-vars:
This module can provoke sizeable inefficiencies for regular expressions, due to unfortunate implementation details. If performance matters in your application and you don't need $PREMATCH, $MATCH, or $POSTMATCH [use -no-match-vars]
