Re^4: I want you to convince me to learn Perl

It's not just the significant whitespace issue; though that is possibly the most frequently annoying.
I hear this way too often and I honestly don’t understand it.
If you already indent correctly (go one unit deeper in a sub-block, one unit shallower when the block ends — and unit is whatever, be it a tab or several spaces, as long as it’s consistent), you won’t even notice the language relies on indentation.
And I sure as hell hope you people indent properly in your non-python code too, already.
That said, Python annoyed me with one thing that Perl — thankfully — doesn’t: run-time errors. Everything you can think of, is going to bite you during run. There’s no strict mode, no nothing to guard you against typos and such. Perl will very happily rattle its chains about stupid things that Python will remain completely oblivious about until you run into it while the code is in motion.

Look around at my code here and you'll see that I am very consistent -- almost anal -- about indentation in my code be it Perl, C whatever. But when I wrote python, it was just to damn easy to end up with:
stuff here
more stuff here
Looks consistent, but is invisibly different. And that is puerile, pathetic and it f'ing annoys me. Frequently.
And quite frankly I don't give a flying fig whether you "hear this way too often". If you don't wanna "hear" it, don't read it.

Gosh, chill... didn’t mean to direct it at you in particular, but there’s simply been plenty of times I’ve heard it and I felt I’d say something about it.
I’m almost exclusively a Perl user, but I’ve spent a few years doing KDE3 stuff in Python, and I guess I just feel weird when people find the white-space thing odd while it felt pretty much natural for me simply because it’s merely about making proper indentation a rule. (Heh, now that I think of it, that even fits in the Zen of Python, “there should be one — and preferably only one — obvious way to do it”)

yep, that's what I meant with "more differences than that". OTOH, wether something is annoying (and how much so), very often is influenced by what you have been using before, or what you are used to. E.g. I had seldom need for anonymous subs, so didn't miss multiline ones :-) | [reply] |

See, those little helpers are our friends. Don't good friends deserve a name? :-)
