The strangeness is that >[n=m] means "the thing on the right reads n
but gets m", while |[n=m] means "the thing on the right reads m but
gets n. Backwards!
Not at all. Or at least I don't think so. All it takes is the right way
of looking at it; I think I have a right way, and I hope it will answer
Malte's question as to how to explain this to an rc novice.
When we write >[2=1], we think of that as "create two by duplicating one",
and view it like an assignment statement (left receives right). When
we write |[2=1], we think "the left process's two gets connected to the
right process's one", and don't use the assignment metaphor.
I think that as long as we think about this in the right way, there
should be no problem.
OK,
John.
