=========================== ===========================
The ``migen.actorlib.ala`` module provides arithmetic and logic actors for the usual integer operations.
If complex operation combinations are needed, the ``ComposableSource`` class can be used. It overloads Python operators to make them instantiate the arithmetic and logic actors and connect them into an existing network. This creates a small internal domain-specific language (DSL).
The ``ComposableSource`` class is a derivative of the ``ActorNode`` class (see :ref:`actornetworks`) and should be used in the place of the latter when the DSL feature is desired.
