"""Implementations of functions which have been introduced
in R since version 3.0.0. The backports are conditionally
exported which results in R resolving the function names to
the version shipped with R (if available) and uses the
implemented backports as fallback. This way package developers
can make use of the new functions without worrying about the
minimum required R version."""
