( #3333=superdoc: print w/replies, xml ) Need Help??

I'm afraid that I would come fairly unglued if I saw such an "economical" attempt to write an if statement in the fewest number of characters. The difference makes absolutely no difference at all to the Perl compiler, but it has the very human difference of being utterly un-maintainable.
Ironically, the original code:
6 < 8 ? $ans = "true" : $ans = "false";
is "un-maintainable" not because it is too short but because it is not short enough! Writing it like this:
$ans = 6 < 8 ? "true" : "false";
is perfectly clear and, by eliminating the (error-prone) repeated use of $ans, maintainability is improved.

Since you suggested an if statement, I certainly hope you're not suggesting replacing it with:

if (6 < 8) { $ans = "true"; } else { $ans = "false"; }
This version has the same dubious violation of of DRY as the original, and so is less "maintainable" than the improved simple ternary version IMHO.

    [Corion]: ambrus: Well, for mathematical notation, I find blackboard much more convenient than a computer. But when inserting text or moving text around, the computer wins obviously
    [ambrus]: But either of these is a big problem in practice, so I'd need to spend like thirty years of my life to solve (a) and five more years to solve (b)
    [ambrus]: Corion: yes, CURRENTLY the blackboard is more convenient
    [ambrus]: and it's not like I want to ban blackboards anyway
    [ambrus]: you already have blackboards and a canvas for projector or overhead transparencies (or positive film slide projector, not used for maths) canvas in the same lecture halls today, and switch in a few minutes between presentations,
    [ambrus]: they're only difficult to use together.
    [ambrus]: overhead transparencies are a nice convenience by the way that mix the two slides, because you can write them in advance and edit them during the presentation easily. but they're not very much in fasion these days.
    [ambrus]: you can even print them.
    [Discipulus]: ambrus i'm trying out MremoteNG which wrap putty and rdp and many other things..
    [Corion]: ambrus: Yes, ideally you would have the ease of overhead projection transparencies and pens drawing on them, combined with the computer generated slide text...
