In my opinion, parameters for custom combining algorithm should be
ANY type, as described in Simon's message "You are free to define
syntax and meaning of combiner parameters as needed for your alg."
By this nature, I think we don't have to worry too much about full
fledged expression for the parameter in this case.

I think this is a different issue.
