Different, yet unambiguous, arguably more so than using "=" for
comparison in most contexts but for assignment in variable declaration.
DoSomething tA and tB
-- "and" treated as a string, since it follows a custom command name
put tA and tB into temp
-- "put" is a built-in command, so "and" is a logical operator (and
isn't "temp" a keyword?)
DoSomething (tA and tB)
-- Parens bypass any attempt to be English-like, forcing evaluation.
