[Catalyst] Catalyst Plugin Setup Call

[Alexander Schäfer]

hi guys,

I'm trying to learn some of the catalyst internals and now I'm stuck  
at some particular code, just cant figure out how it works.

The code can be found here:
http://dev.catalyst.perl.org/browser/trunk/Catalyst-Runtime/lib/ 
Catalyst.pm#L825

It's the one calling all plugins' setup subs.

I wrote a sample script which should simulate the whole process  
involed in loading and calling plugins setup.

As you can see, I've gotten two variants, the NEXT variant works as  
expected (lucky guess), the other one just got me totally lost. I  
thought it would be right the same as NEXT, and then redo all plugins  
until runtime comes again (evil thought), but instead it stopped at  
the first ISA entry.

Anyone can explain me that behaviour and then the behaviour of catalyst?
Any help would be appreciated!

bye Alex
