transactions in order to reduce the number of possible states make
make reasoning about them easier (in the spirit of the mutable state
discussion of [1]) and thought that Clojure's dosync + refs might be
the ideal way to do
I would have hoped that changes to refs during an transaction wouldn't

liked the code to print 1, then 2). This way, the view of the
program's state would always be guaranteed to be consistent, even
during a transaction, and

you usually don't want that. When you start working on more than one value
in a transaction (and
