in thread Words and Numbers to hash

this worked for the most part however, the first value I am getting is:

$VAR1 = 'Opp Avg Score Margin'; $VAR2 = '10.8'; ...

Instead of all the stuff leading up to it:

Points/Game 80.5 Opp Points/Game 69.7 Avg Score Margin 10.8

Why would you think that would be?

    You may be expecting the hash to preserve the order of the fields extracted from the string. It won't. The only 'order' in a hash is the key/value paring of each hash element. You must somehow impose your own order on top of this inherent order. Perhaps see Tie::IxHash.

[choroba]: Good morning, Monks!
[Corion]: And a good daypart to you as well, Lady_Aleena !
[robby_dobby]: Hey monkeys, do you ever get the realization that you're all waking up to chaos? I suppose not :P
[Lady_Aleena]: Good morning Corion, I hope you have a wonderful day as well. 8)
[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
