autobox::CORE defines methods for core operations such as join, print, most everything in perlfunc, some things from Scalar::Util and List::Util, and some Perl 5 versions of methods taken from Perl6. These methods expose as methods the built-in functions for minipulating numbers, strings, arrays, hashes, and code references. It can be handy to use built-in functions as methods to avoid messy dereferencing syntaxes and parentheses pile ups. WWW: https://metacpan.org/release/autobox-Core
