in reply to JSON saving regex?

The problem is that qr/.../ produces a Regexp object (try ref(qr/.../)).

If you know where all the regexes are in your structure, you could convert them all to strings before calling to_json() on them.

Or you can do:
{ package Regexp; sub TO_JSON { my $regex = shift; $regex = "$regex"; return $regex; } my $json = JSON->new->convert_blessed; print $json->encode(qr/.../);
as documented in JSON
