The reason why people keep coming back to a series of comparisons
(actually more general: a series of branch on tests) is that a series
of comparisons is behaviorally equivalent to a switch.  Written in
appropriate style it's obvious that it is intended to have the effect
of a switch.  The code implementing a case is given "naturally" after
mentioning the case.  Given all that, it seems unnecessary to add new
syntax.

Starting from that summary of the thread, what are you trying to
argue?
