in reply to Komodo 4.x
Hello, this is Shane from ActiveState, lead for Komodo. While I agree that it looks like we don't do much for Perl in Komodo at this point, it's largely due to the fact that it (and Python) were the first languages that we supported deeply feature-wise.
So while there are not major new features specific to Perl in K4, if you're using Perl on the web, there are lots of useful improvements for you.
For Perl 6, well there isn't really an approaching 1.0 release of it at this time and only bleeding edge pickup on it. If someone wanted to add Perl 6 syntax support to Komodo, it can be done via UDL (our own language definition syntax). Once things progress further with Perl 6 we ***WILL*** be adding support.
BTW, upgrades from 3.5 are much less than the list price, see our store for details.
