It's lame, but the idea behind the original design of "pack/unpack"
was to have the argument lists look the same. So, to send a variety
of (known-type) data down a send/receive channel or whatnot, one could
use "pack tea for 2" and a corresponding "unpack tea for 2".
Of course, that in the unpack side, only the types were significant,
is stylistically wierd. It just seemed less wierd than any other idea
I had at the time.
