You cannot have true OOP without tail calls.  This is not a matter of
nitpicking.  See Matthias Felleisen's ECOOP invited talk slides.

(You can't have true FP without tail calls, either, but I assume
everyone here knows that.  A few seconds' inspection clarifies that
both of these "can't have"s are for the same reason.)
