a = b = 1 just syntactic sugar?

I was thinking only of unusual circumstances.  I certainly wouldn't
want to write unidiomatic code just for the sake of setting two
variables at once.  But I can think of places like lambda-expressions
where this could be very useful, and possibly make the code clearer
than using an alternative style.  If, in practice, it turns out to
make the code less clear and less maintainable, then of course I
wouldn't do it.
