in reply to How scalars work (about numbers, text strings, and binary strings)

One way to keep binary strings seperate from text strings when you have to deal with both is to use hungarian notation.

my $bin_msg = ...; my $txt_msg = decode($encoding, $bin_msg);

See Making Wrong Code Look Wrong for more on the subject.

(I usually use "bytes" and "chars". I used "bin" and "txt" here to be in line with your diagram.)

    That's a great idea, and I have done it in a few examples. I'd have to fight my old habits in order to do such a thing in actual code, though.

    Maybe it would be easier to do with single-letter prefixes. "u" for Unicode, perhaps. Feels better than "t" or "c" (I read "c" as "count", and would expect a number).

[Corion]: A good morning to you too ;)
[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.
