I agree. I've tried to think of a better alternative name, but without
much success.

Those seem pretty unmemorable and content-free, though. Any other ideas
out there?

PS: btw, I have realized that the seemingly obvious algorithm for
choosing a delimiter string for given text is wrong. I had imagined it
as "try $$, $Q$, $QQ$, $QQQ$, etc, until you find a delimiter not
present in the given text string". This is not right because, for
example, if the string ends with $Q then $Q$ is not a usable delimiter
($Q$...$Q$Q$ would be misparsed). The simplest correct algorithm is
"try $, $Q, $QQ, $QQQ, etc until you find a string not present in the
given text string; then use that with a $ appended".
