297297The ``pragma[inline_late] `` annotation must be used in conjunction with a

303304For instance, in the example below, the ``pragma[inline_late] `` and
304305``bindingset[x] `` annotations specifiy that calls to ``p `` should be join ordered
305306in a context where ``x `` is already bound. This forces the join orderer to
306- order the ``q(x) `` call before ``p(x) ``, which is more computationally efficient
