BTW, Peter, I guess I should have said "I misunderstand, but it can be
legal if you consider it part of the statements", since it appears the
author did intend it to be part of an expression.

What would be the advantage of that over this?
. x = sqrt(a) + sqrt(b) where:
. a = 2.0
. b = 3.0
Where would making "where" part of an expression rather than part of
the statement help? Can you think of a place? ("That it makes Python
more like LISP" is not a good enough answer for me, BTW. But feel free
to try. :)
