Has anyone else encountered this/have any suggestions?

Store Regexp::English objects? :)

I once patched YAPE::Regex::Explain to recognize the new syntax (?^i:i) and (?i-xsm:i) but the whole thing left me disgusted with the obscene amount of catching up required just to tokenize the regex -- something the engine already does

Maybe you could use re::engine::Hooks or probably overload to hook-into it globally

Maybe see example in http://perl5.git.perl.org/perl.git/blob/HEAD:/lib/overload.t

It works with pure-perl but not YAML::XS

#!/usr/bin/perl --
use strict; use warnings;

print qr{yo}usim, "\n";
$::yo++;
print qr{yo}usim, "\n";
$::yo--;
use YAML::XS;
print YAML::XS::Dump( [ qr{yo}usim ] ), "\n";


package Regexp;
use Data::Dump;
sub ixsm { #~ (?s-xim:s)
    my( $i )=@_;
    my %onoff = ( qw/ s 0 i 0 m 0 x 0 / );
    
    $onoff{$1}++ while $i =~ /(.)/g;;
    
    delete $onoff{$_} for qw/ o a l u d /;
    
    my @off;
    my @on;
    while( my($k,$v) = each %onoff ){
        push @on, $k if $v;
        push @off, $k if not $v;
    }
    my $on = join'',@on;
    my $off = join'',@off;
    my $ret = "(?$on";
    $ret .="-$off" if length $off;
    $ret;
}
use overload '""' => sub {
    my( $self_operand_overloaded, $other_operand, $other_operand_was_o
+n_the_left_side ) = @_;
    my( $patt, $mods ) = re::regexp_pattern( $self_operand_overloaded 
+);
    $::yo and return ixsm($mods).':'.$patt.')';    ## oldstyle
    return $self_operand_overloaded; ## modern
};
__END__

Seems YAML::XS doesn't process overloads, peeks inside like Devel::Peek

Thanks for checking that avenue. I was pretty sure YAML::XS was going to be a problem. I think it's going to be easiest for me to start saving regexes as strings instead of perl objects. I will also have to delete any regexes I accidentally load from old data, because if I read/write them a few times, they eventually become unparsable. The bug hit when

    match: !!perl/regexp (?i-xsm:OK\ Server\ Connection\ 1\.001)
[download]

became something like

    match: !!perl/regexp (?-u(?-u(?-u(?i-xsm:OK\ Server\ Connection\ 1
+\.001))))
