In the meantime, use this as perl -MRegexp::Q -ne "print if /\pQ.+\pQ/" :)

package Regexp::Q;
use overload;
sub import {
    shift;
    die "No argument to ${\__PACKAGE__}allowed" if @_;
    overload::constant 'qr' => \&convert;
}

sub invalid { die "/$_[0]/: invalid escape '\\$_[1]'"}

use vars::i '%rules' => (
    '\\' => '\\', 
    'pQ' => qr/['"`]/,
    'PQ' => qr/[^'"`]/,
);


sub convert {
  my $re = shift;
  warn "rei is $re";
  $re =~ s' \\ ( \\ | [pP]Q )  ' $rules{$1} or invalid($re,$1)   'sgex
+; 
  return $re;
}

package main;
unless(caller){
    BEGIN{import Regexp::Q}
    print "YAY!$/"
        if q~PodMaster asked me "Do you like parachute pants?"~ =~ /\p
+Q/;
}
