Transients
==========

*Transients* is a concept borrowed `from Clojure
<clojure-transients>`_, with some twists to turn make more idiomatic
in C++.  Essentially, they are a mutable interface built on top of the
same data structures the implements the immutable containers under the
hood.

These can be useful for :ref:`performing efficient batch
updates<batch-update>` or :ref:`interfacing with standard
algorithms<std-compat>`.
