Hi Boaz:

If I say:

>From A ...

and the class graph contains no A, I have clearly a typo in
my strategy or class graph. If we don't make it fatal,
the Java compiler will after a minute or two.

maybe: I tend to think of a strategy graph as encompassing many
possibilities (say with different choices of source/target). when one
possibility is chosen with a specific class graph, it may be the case that
others become useless. making this kind of error fatal disallows this kind
of programming. this may be the right approach: my position in this regard
is not strong.
