hi,
I have one app in wich to do my job i have to make alot of if/unless-else chained checks and in most of the cases the actions after that are no more than 3, not everytime but ..!!
Because after a while they become very ugly I want to find a way to simplify the things and make the code more strightforward/non-hairy ;).
But let me show u simple example
$o->check(...);
unless ($o->state) {
   action..
} else {
   $o->check(...);
   unless ($o->state) {
     action....
     $o->blah()
     if ($o->state) {
        actions..check..
          unless($r->state) {
             and so on...deeper and deeper...
          }
     }
   }
}

Most of the checks are on $object->state(), but not nececerily.
For the sake of it things become more underadable when I add alot of comments to clarify the things ;))
I'm looking for an idea how to make this easier for the users of my module. So if the idea adds more complex code/behavior on the Class i'm building it is doable. My main goal is to simplify the task of the other programmers.
I was thinking something on the line of prolog like syntax or I see some lang have 'assert', (cant figure out the idea exactly) !!. But it has to stay perl, not something parsable, 'cause sometimes there is very convulved logic to be added.


10x alot in advance
