The comparison functions work on any values whose type Go defines as
comparable. For basic types such as integers, the rules are relaxed:
size and exact type are ignored, so any integer value, signed or unsigned,
may be compared with any other integer value. (The arithmetic value is compared,
not the bit pattern, so all negative integers are less than all unsigned integers.)
However, as usual, one may not compare an int with a float32 and so on.
