The second one doesn't bug me. Unary minus on a sequence is meaningless. The first is a bit odd. When using the * operator for sequence repetition, I don't expect it to have the same commutative property as multiplication. IOW, "seq * n" makes sense but "n * seq" is a bit weird. Also, I'm not clear on the rationale for transforming negative repetition counts to zero instead of raising an exception. OTOH, neither of these has EVER been an issue for me or anyone I know.
