Quite right. A switch/case statement isn't at issue for PEP 308, 
and I was incorrect to label this proposal as such -- switch/case
is a block level construct which contains statements.  I'm not
proposing that.  

This proposal is for a select/when *expression* which is simply 
a generalization of a terinary operator, and equivalent to 
some of the "elif" like options on the table.  So, this 
proposal fits right in with the spirit of the PEP.

Well, I'd like to see what people think; I guess Guido can
take the "late comer" status into consideration.  ;)

Sorry for picking the wrong words,
