Agreed, do it in Perl 5.
in reply to Develop in Perl 5 Or Wait for Perl 6?
Perl 6 is all about Doing It Right, so has no external deadlines. It's a good idea not to rely on it, as it's already blown past timelines people have estimated for it. It's not someone's job to hit a date, and quality is (correctly) the chief concern, so it's hard to predict when it'll be ready.
But, I would recommend making your design modular where possible, so you can port it over piecemeal when Perl 6 is ready. It's a design goal to be able to run Perl 5 and Perl 6 modules together, and you can rely on that.
All of us Perl Developers who are not Developers of Perl wish Perl 6 were ready sooner - but we're glad we don't have to pay the price of corners being cut to hit someone else's date.
