While we could fabricate something, we don't have a good use case in
our requirements & use cases document that requires it.

What I found interesting was Jeni's examples of computing parameter
values from different parameters and not inputs.  They didn't actually
get values from inputs but instead just choose between two parameter
values using some expression.

Maybe we could address that issue and remove the need for expressions
to handle that case?  Then we can push computed parameters on inputs
to a future version.
