Personally, I don't think an acknowledged limitation of a library

I find it helpful to have it open as a reminder. RT is my to-do list. :-)

Personally, I do.

It's marked as a limitation that is not desired, and should be eliminated.
That's not the same as a limitation that's going to stay.

this. Absent a patch or some complaint, I will close this ticket in 7

It's an unresolved bug that Storable can't store regular expressions.
We track open bugs in RT.

By that measure the ticket *should* remain open, even if there has been
no progress on fixing it for some years. To close it would be lying to
ourselves. The goal isn't minimise open RT tickets, it's minimise bugs.

I find this an interesting message. FORMLINE I mostly understand, GLOB
is a little less understandably but sill in the "well I can see the
point.." category, but REGEXP I actually dont get at all.

The only circumstance that a REGEXP object would not make sense in
Storable is when it is bound to a non Perl regex engine.

Other than that, it seems to me that the semantics are clear: do the
same thing that Data::Dump::Streamer does, and do the Storable
equivalent of

qr/$pattern/$modifiers

$ perl -MData::Dump::Streamer -e'Dump { foo => qr/bar/i }'
$HASH1 = { foo => qr/bar/i };

Although I will say that while I think the semantics are clear for
REGEXP objects, the implementation in Storable is not to me.

cheers,
Yves

It was not really advertized, but starting with Storable 3.06 which is part of perl 5.27.9 and later there's experimental regexp support built in. The above code line does not fail anymore, and seems to do the right thing:

$ perl5.27.10 -e 'use Storable; use Data::Dumper; warn Dumper Storable::dclone qr/foo/;'
$VAR1 = qr/foo/;

Now it would be nice if there was a CPAN release of this Storable version, so older perls can also use the new feature.

Last CPAN release was 2014 - a long time ago. I'll work on that. Thanks

This was released to CPAN in Storable 3.08.

Closing.
