"""Generic Reproducible Parallel Backend for 'foreach' Loops.
Provides functions to perform reproducible parallel foreach loops, using
independent random streams as generated by L'Ecuyer's combined
multiple-recursive generator (L'Ecuyer (1999),
<doi:10.1287/opre.47.1.159>). It enables to easily convert standard
%dopar% loops into fully reproducible loops, independently of the number of
workers, the task scheduling strategy, or the chosen parallel environment
and associated foreach backend."""
