So the problem is that $self is not an object instance, but rather the class. One way to solve this is to use builder instead of default like so.

has 'serverLocation' => (is=>'ro',isa=>'Str',builder =>'buildServerLoc +ation'); sub buildServerLocation { return "$Bin/lib/selenium-server-standalone-2.0b2.jar" } sub FOREIGNBUILDARGS { my $class = shift; my %args = ( @_ == 1 ? %{ $_[0] } : @_ ); $args{serverLocation} ||= $class->buildServerLocation; $args{host}//="localhost"; $args{port}//=4444; $args{browser}//="*firefox"; $args{browser_url}//='http://wwww.google.com'; return %args; }

    [Corion]: Yesterday I encountered an interesting data structure problem. I have a remote program that emits events, and my client listens for these events with one-shot callbacks, that is, I register the callback and if the event gets generated that callback ...
    [Lady_Aleena]: robby_dobby, every day. Chaos is my life with few controls.
    [Corion]: ... gets called once. The data structure for that is just a hash of arrays, mapping the event type to a queue of registered one-shots, and the first one-shot from the queue gets removed and called.
    [Corion]: But now I want to register a one-shot for two events, of which only one will arrive, so my data structure doesn't work anymore...
    [Lady_Aleena]: Corion, ouchy.
    [Corion]: (maybe I should write this up as a SoPW) - currently, the "most efficient" data structure I come up with is a single array which I scan for the first fitting one-shot. Not efficient but I don't expect more than five outstanding one-shots anyway
    [choroba]: can't you create a meta-key corresponding to the disjunction of the events?
    [robby_dobby]: Corion: Heh. This whole thing smells of Strategy Pattern or MVC pattern.
    [Corion]: And performance linear to the number of registered one-shots doesn't feel that bad. Maybe I should collect statistics on how many callbacks are outstanding ;)
    [Corion]: choroba: Yes, but the longer I thought about efficient hashes mapping the event type back to their callbacks, and how to keep them in sync, the more I thought that all that optimization might just not be worth it, even if it's horribly inelegant
