To Bit Or Not To Bit

Ah, the classic programmer double entendre. What we're looking at is [2b | !2b] followed by "That is the expression." It's Shakespeare's famous "to be or not to be" dilemma rewritten as a bitwise OR operation. The "2b" is hexadecimal (base 16) for 43 in decimal, and the exclamation mark represents logical NOT. So you're literally performing a bitwise OR between "to be" and "not to be" in code. The punchline is the perfect deadpan delivery: "That is the expression." Because, well, it literally is an expression in programming terms. Whoever came up with this probably felt extremely clever while their coworkers groaned audibly.
