Strictly necessary for function, no. Quicker and clearer, yes.

Like a bookmark (or locking a tab) for a page you reference frequently. Perl is not so good as statically compiled languages at sub-expression elimination.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
