Wait a minute -- that isn't a path expression there!  The '|' is not
supposed to change the rules for evaluation of the subexpressions!  If
'int' or the like were somehow avaialbe at module scope, or via
'options' or another top-level name, then they should be called *when
they are the last item in a path expression*.

The test was actually correct beofore: because tne PathExpression, 'x',
raises, the PythonExpression, 'int', is evalutated.  The result of a
subexpression is not suppoeed to be called,
