Traditionally WHEN is an output limiter and WITH is a selector, so they occupy 
different branches of the process. But with a SELECT SAVING that difference 
becomes blurred, so I would vote for a WHEN to be allowed in that case.

Of course on unidata it would no doubt have to be on some dumb UDT.OPTION to 
preserve compatibility.
