It's elready defined semantics. $ means length. If you want different
semantics, use different means to express it. Objects in container can be
numbered from 1, numbering can have gaps, so $-1 can be meaningless, or entire
collection can be unordered like hashtable, so the last element can be
meaningless, or keytype can be of complex type, having nothing in common with
numbers, you just use different means to work with it.
