A selection of general-utility list subroutines
This package is based on the package 'perl-Scalar-Util' from project 'devel:languages:perl'.
List::Util contains a selection of subroutines that people have expressed would
be nice to have in the perl core, but the usage would not really be high enough
to warrant the use of a keyword, and the size so small such that being
individual extensions would be wasteful.
