On further reflection, the conditional expression cannot be merged with a
simple redefinition. The conditional expressions have the "shortcut"
feature where not all of the expressions need to be evaluated. The
conditionals will still need to be a special case because of that.
Also on further reflection .. perhaps the conditional case could drop the
shortcut feature. In other words: all the expressions are evaluated, and
if any of them are true then the THEN/WHEN path is taken.
Especially in the select case the expressions are likely constants anyway.
One loses the 'shortcut' ability -- but even in NetRexx I was a bit worried
that it wasn't very general. So a different approach to shortcuts might
work better.
