Offhand, I can think of no other cases in which a single-character variable name is "reasonably appropriate",

How about the long standing convention of my( $r, $g, $b );?

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.
"Too many [] have been sedated by an oppressive environment of political correctness and risk aversion."
