transient collections collect values in an internal (mutable) data
structure and periodically add them in batch. So you will typically see the
identical value returned for a while, then it will change.
You should *always* use the return value - the same usage pattern as with
persistent collecti
The answer is that you should treat them as you would persistent
structures. It's true that they don't always change, but they may
eventually change and without notice. For vectors this will be somewhere in
the range of once every 32 conj! calls, but could change in a future
version of clojure, so
While doing operations on transient collections, I've noticed that the
result of assoc! or conj! is always identical to the original structure
(i.e. it satisfies "identical?", and is not merely equivalent).
Is this always the case, or can the return value of assoc! or conj!
sometimes be a diff
