Yoda speaks in reverse "Stopped they must be; on this all depends".
"if (0 < len)" says "if zero is less than len", which is in reverse,
as reverse as "if 1.50 is taller than you". It's all reversed: "if you
are taller than 1.50", "if len is greater than zero", "They must be
stopped; all depends on this".
