I find it hard to understand your non-grammatical English, but I presume you
want to imply that you don't use short-named variables such as "$a" and "$b" in
production. What I wanted to say is that you should never use them except with
conjunction with sort and friends (like those higher-order routines from
List::Util or List::MoreUtils).
That's because lexicalising them will cause the original $a and $b to become
inaccessible. So don't do that because this will encourage bad practises and
people sometimes learn from code like that, which they find in web searches.
So please - NEVER LEXICALISE $a AND $b. Comprendre?!!
