in reply to RFC:A brief tutorial on Perl's native sorting facilities.

Fine post. Some random nits...

That it is about as fast as you are likely to get; that it is built-in to language so always available; and that it understands Perl internals; does.

I fail to parse that sentence. I also fail to parse the updated version:

That it is about as fast as you are likely to get, it is built-in to language so always available, and it understands Perl internals, do.

What does the final ",do" do?

So, sorting data when you want to sort according the the entire value of each element of the array or list is easy.

I'd rather not use the statement-modifier mode here, instead I'd say (s/the the/the/):

_($_=" "x(1<<5)."?\n".q·/)Oo.  G°\        /
                              /\_¯/(q    /
----------------------------  \__(m.====·.(_("always off the crowd"))."·
");sub _{s./.($e="'Itrs `mnsgdq Gdbj O`qkdq")=~y/"-y/#-z/;$e.e && print}

    Okay shmem. That first sentence was always a mess, and correcting the grammer whilst leaving the structure intact didn't help much. Is this any better?

    How sort actually works internally doesn't really matter. What does matter is that being built-in to the language, it understands Perl's internals, is always available and about as fast as you are likely to achieve.

    s/the the/the/ should be s/the the/to the/. That I haven't noticed this before, having now read and re-read this dozens of times, does not surprise me. That many other pairs of eyes have looked right past this, does. Welcome to my world.

    Corrections made. Thanks.

      Nice. Now I've got it - the "..., does." was refering to the "doesn't matter" from the previous sentence. Anyways - it's way clearer now.

      clap, clap, thank you - having stuttered as a child I just stumble over repeated words. And, good you showed me the "...,does." construct again ;-)
