We were thinking about implementing it that way, but implementing it
like it is (no limitation about the number of parameters) appeared at
the time a more efficient approach. I like the relay implementation
since it's 100% portable while this one isn't. However, and I repeat
myself here, I'd like to know why the code can't work.
