Yep, and Sanjiva suggested renaming this to "interaction" as well (which
I liked).

If you can't distinguish between message exchanges / interactions /
operations, then what good are they?  See my recent message to Amy [1].

The fact that "interfaces" happen to combine "operations", and that you
COULD if you wanted to then map those "interfaces" to things that look
like objects/classes, is, while true, orthogonal to the desire to
utilize and identify the operations themselves.
