But in Java (as in its familial predecessors), recursion *is* worse
than in Scheme.  Even if you write a recursive call in tail-position,
the lack of tail-call optimization means you do pay a price.  If you
are a Java programmer, you have no choice but to add this to the set
of things you must worry about.
