I knew about "short-circuiting" but you could have evaluated the right operand
first and then if false, skip the first one. What I didn't know, is that unlike
other operators whose operands' evaluation order is undefined, `&&`, `||`, and
`,` have their left operand evaluated first and then their second one.
