Re: [Catalyst] Moose's make_immutable in Catalyst classes

Generally Catalyst components are only initialised once (i.e. they're scoped to the lifetime of the app), so there is no speed benefit to immutable in this case (actually, it's probably a startup speed reduction), but I still tend to use it for the safety… So it's entirely optional, in classes which implement ACCEPT_CONTEXT (and so are constructed once per request), you will see a speed benefit from doing it, but this is the less unusual case..

Re: [Catalyst] Catalyst-Runtime 5.90017 isntallation problem
Just to add that version 5.90018 has been released which I guess fix that issue.

Re: [Catalyst] Progress bar

[Catalyst] [ANNOUNCE] Catalyst-Runtime version 5.90018
I'm pleased to announce Catalyst version 5.90018! This release solves pointless test failures when installing Catalyst due to recent changes in HTTP::Message. You may not consider this a mandatory upgrade unless this issue is biting you. Thanks!
