    """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."""
