Wishlist of PL/Perl Enhancements for PostgreSQL 8.5

I'm planning to work with Andrew Dunstan on some enhancements to PL/Perl
for PostgreSQL 8.5.

I've written up some initial proposals here:

  http://blog.timbunce.org/2009/10/05/wishlist-of-plperl-enhancements-for-postgresql-8-5/

I'd welcome any feedback on those, and any other suggestions you may have.
(Either here, on the blog, or direct to me - I'll post a summary.)

Thanks.

Tim.
