math/Math-Random-ISAAC-XS.
This module implements the same interface as Math::Random::ISAAC and can
be used as a drop-in replacement. This is the recommended implementation
of the module, based on Bob Jenkins' reference implementation in C.
Selecting the backend to use manually really only has two uses:
* If you are trying to avoid the small overhead incurred with
dispatching method calls to the appropriate backend modules.
* If you are testing the module for performance and wish to
explicitly decide which module you would like to use.
