"::" Could be confused with Haskell's type declaration operator.
If we want to avoid confusion with the walrus operator, "options!?=..." is a decent
alternative. It can be remembered as "if not there? equal to" [! there? =].
"<~" isn't OK because "<" is a binary operator and "~" is a unary
operator, so that's the same as "< ~".
