If the subparsed string includes an unmatched ')', this could confuse the parser into finishing the expression and effectively exiting the subparse without cleaning up (including popping the context) To avoid that, create special bracketing tokens only generated for a subparse and update the grammar to use those tokens in the cases they might be used in a subparse. This is an updated version of the patch that moves the FUNC rule to where the original rule was and adds a test for non-regexp subparses. ----------------------------------------------------------------------- -- Perl5 Master Repository
