  pardon me for insisting, but definitions, algorithms, implementations,
  and _solutions_ are easily described as recursive.  my question relates
  to calling things recursive _problems_.  if it is "a problem for which a
  recursive solution is deemed most aesthetic", it is just meaningless, but
  if it actually means something specific, I'd like to know.  I find the
  term puzzling, apart from the more or less meaningless interpretation
  that doesn't refer to the problem at all.
