Maybe it would be enough to represent the example "where" problem more
fairly on its own terms. The non-working example has us writing
f = State $ \ x -> y
where y = ... x ...
but the "where" side of the aisle is supposed to detest lambdas, so would
be unlikely to have taken this particular route anyway.
I'm not saying "ergo, there is no problem after all", only that it's not
all that well taken.
