final class TRef[A] extends Serializable
A TRef is a purely functional description of a mutable reference that can
be modified as part of a transactional effect. The fundamental operations of
a TRef are set and get. set transactionally sets the reference to a
new value. get gets the current value of the reference.
NOTE: While TRef provides the transactional equivalent of a mutable
reference, the value inside the TRef should be immutable. For performance
reasons TRef is implemented in terms of compare and swap operations rather
than synchronization. These operations are not safe for mutable values that
do not support concurrent access.
