Returns a string representation of the transactional value in this instance for debugging convenience.
Returns a string representation of the transactional value in this
instance for debugging convenience. The Ref reads (and writes)
performed while constructing the result will be discarded before
returning. This method works fine outside a transaction.
If this method is called from within a transaction that is already
doomed (status Txn.Rolledback), a string describing the reason
for the outer transaction's rollback will be returned.
Returns some value that is suitable for examination in a debugger,
or returns a Txn.RollbackCause if called from inside a doomed atomic
block.

Takes an atomic snapshot of this transactional set.
Returns the TSet perspective on this transactional set, which
provides set functionality only inside atomic blocks.
(Changed in version 2.8.0) + creates a new set. Use += to add an element to this set and return that set itself.

(Changed in version 2.8.0) ++ creates a new set. Use ++= to add elements to this set and return that set itself.
(Changed in version 2.8.0) - creates a new set. Use -= to remove an element from this set and return that set itself.

(Changed in version 2.8.0) -- creates a new set. Use --= to remove elements from this set and return that set itself.
(Changed in version 2.8.0) Set.map now returns a Set, so it will discard duplicate values.
(Changed in version 2.9.0) The behavior of scanRight has changed. The previous behavior can be reproduced with scanRight.reverse.
(Changed in version 2.9.0) transpose throws an IllegalArgumentException if collections are not uniformly sized.
