The right time to start a project? made me wonder whether there is a repository of "Do's and Don'ts in Perl 5" that would facilitate a future migration to Perl 6? Something you could look at if you're starting a new Perl 5 project?

I realize that there are a number of Perl6:: modules out there already, but I would understand it if you wouldn't want to use those in production code.

I'm more thinking along the lines of:

• Don't use GLOBs in new Perl code if you can. If you must, hide them in easy to update subroutines.
• Don't use formats if you can. If you must, make it so that it can be easily replaced by an external module handling the format (how would you do that?)
• ...

Is there such a repository already? If not, would it make sense for the Perl Monks to create and maintain one?

Summary:

1. It seems the general consensus is that such a repository is not needed now (or ever for that matter).

2. It is generally advised not to use XS or Inline::C (if you must, then only use Perl 5 macro's).

3. Don't do anything Abigail-II is doing in JAPH's ;-)

4. Don't use %_ .

5. Don't use the X:: namespace.
