Of course I'm not the best person to talk about this. I read a little about Perl 6, looked a little to Parrot... nothing more.

But, knowing Larry Wall (well, I don't know him) I can expect that Perl 6 supports procedural programming as well as Perl 5.

Now, regarding other tools being available as OO modules will probably lead you to learn a little about OO.

To learn OO I would suggest the O'Reilly book Learning Perl Objects, References & Modules by Randal L. Schwartz (check this page)
