in reply to Stop suggesting to upgrade perl

The problem is that for some classes of tasks (e.g. Unicode support), the older version of Perl are insufficient. New versions usually bring new functionality that is not backpropagated to the older versions.

    If some task is impossible to implement for specified version range, one should mention that (and possibly explain), instead of recomending to upgrade to random (or latest) version.

    There is also difference between "upgrade perl" and "raise minumum perl version requirement", former is indication that person think there is only once instance of code, and, perhaps, recommends just a random new version.

    Unicode in Perl works mostly fine since 5.8.8.

      Except for the "Unicode bug", which was solved a bit later.

        Which is not a big problem:

        perlunicode
        For Perls earlier than those described above, or when a string is passed to a function outside the subpragma's scope, a workaround is to always call utf8::upgrade($string)

        Anyway, there is an example of node, where, thankfully, people *did not* suggested me to upgrade perl: Force ASCII regexp for all perls 5.8+ (perhaps because perl version was in post title)
