in reply to Re^4: Dynamic variables
in thread Dynamic variables

I find that, especially with complex data structures, the -> notation can clarify things by seperating my identifiers.

You also pick as examples of dereferencing notations that can tend to look complex to an inexperienced programmer whether they are references or not. All of the examples you cite for complexity can be rewritten using less confusing notations.

for (0 .. $#{$aref}) {} # or for (@$aref) {} @{$aref2} = ...; #or @$aref2 = ...;
I'm not sure why you don't show that the curly braces can be left out during dereferencing.

    I find this view rather bizarre. I think the balanced nature of subscript delimiters clarifies things pretty well as it is. To each his own, I suppose.

    This statement may be true, but your for loop example is not the same as mine. Looping on array indexes and array elements is not the same thing. Sometimes you need the index as well as the value it points to.

    I generally use the braces for clarity. I suppose that's a bit of a contradiction over my earlier claim of trying to avoid visual noise, but there it is. You're probably right that I should have mentioned it, though. I just didn't think to do so.

    That said, this whole conversation thread is kind of strange. Am I actually defending the use of plain data structures over references? What's the point? You can use references 100% of the time if you want, but I'll stick to the regular type of variables.

[perldigious]: That stuff can hit fast... like what we just got where I'm at. Saw a few people who had slid OUT of the roundabout I have to drive through to get to work, not used to the ice yet, take awhile to get the hang of it again and make vehicle adjustments.
[stevieb]: man, when the roads are glare ice, I don't even bother going to work or out... unless I absolutely have to, or was already out in the first place
[choroba]: Tire chains are mandatory here in mountains, and the only unprepared each year are gritters
[stevieb]: I have a 3 day winter survival kit in my vehicle in the event I get snowed in in the mountains (which has happened before due to avalanches closing the roads (and once in the summer due to a massive forest fire that trapped us
[perldigious]: a handful of people in my work area did not make it, but I live pretty close and it's flat the whole way, so I didn't have any trouble. The roundabout is the worst thing I have to negotiate.
[thezip]: G'day all!
[perldigious]: Well, that and dodging the people who forget how ice works right away. :-)
[stevieb]: hey, thezip
[perldigious]: I don't miss having to drive up and down in elevation on roads that are iced over, I white knuckled gripping the steering wheel every time I had to where I used to live.
[perldigious]: So I don't envy you mountain guys if you have to drive in the winter, even with tire chains.
