To me, it says "give me the first element", not "give me any (an
arbitrary) element" or "give me a random element".
Does anyone have a use-case for retrieving a single arbitrary element of
an arbitrary sequence, without caring about any other elements? Is this
really such a common operation that we need to consider it part of the
interface for all collections? I doubt it.
