How much does CF *really* need? Pseudocode:
<cfif variables.ZIPCode LT 93711>
...blahblahblah...
<cfelseif mySwitch(variables.ZIPCode, "93712, 93713 TO 93940, 93950,
94086 TO 95050")>
...blahblahblah...
<cfelseif variables.ZIPCode GT 93711>
...blahblahblah...
</cfif>
You just have to write mySwitch() once and put that in your standard UDF
includefile.

I always believed the whole point of a switch statement was that only
the switch side had to be evaluated as an expression and the case sides
were simple values, thereby greatly reducing the amount of processing.
