Yes, this has been discussed extensively in the past....I think the
convention is to use the ctor functions if you're passing data
dynamically, otherwise if dealing with constants the literals should be
just fine...In the case just replace the set literal with (hash-set ...)
or (set ...).
hope that helps...

Of course you can even replace rand-int by a function which is
actually guaranteed to return different values on consecutive calls,
e.g. a closure over an atom.
