Ah, wait! Don't care about my last message. I didn't read carefully
enough.

I don't believe it's possible to do the thing that you are looking for
that way. You best shot is o create a getValue()-function that do all
the calculation, and then create value2freq(), value2q(), value2gain etc
(that calls getValue()) when you need them.

Something that could make this easier is a way to insert arbitrary code
into spork-statement:

spork ~ { /*mycode*/ };

but that's probably not here in the next few releases.
