This feature is new in Perl 5.16. You can take references to these and make aliases. However, some can only be called as barewords; i.e., you cannot use ampersand syntax (C<&foo>) or call them through references. See the -C<shove> example above. These subroutines exist for all overridable -keywords, except for C<dump> and the infix operators. Calling with +C<shove> example above. These subroutines exist for all keywords except the following: + +C<__DATA__>, C<__END__>, C<and>, C<cmp>, C<default>, C<do>, C<dump>, +C<else>, C<elsif>, C<eq>, C<eval>, C<for>, C<foreach>, C<format>, C<ge>, +C<given>, C<goto>, C<grep>, C<gt>, C<if>, C<last>, C<le>, C<local>, C<lt>, +C<m>, C<map>, C<my>, C<ne>, C<next>, C<no>, C<or>, C<our>, C<package>, +C<print>, C<printf>, C<q>, C<qq>, C<qr>, C<qw>, C<qx>, C<redo>, C<require>, +C<return>, C<s>, C<say>, C<sort>, C<state>, C<sub>, C<tr>, C<unless>, +C<until>, C<use>, C<when>, C<while>, C<x>, C<xor>, C<y> + +Calling with ampersand syntax and through references does not work for the following functions, as they have special syntax that cannot always be translated into a simple list (e.g., C<eof> vs C<eof()>): -C<chdir>, C<chomp>, C<chop>, C<each>, C<eof>, C<exec>, C<keys>, C<lstat>, -C<pop>, C<push>, C<shift>, C<splice>, C<stat>, C<system>, C<truncate>, +C<chdir>, C<chomp>, C<chop>, C<defined>, C<delete>, C<each>, +C<eof>, C<exec>, C<exists>, C<keys>, C<lstat>, C<pop>, C<push>, +C<shift>, C<splice>, C<split>, C<stat>, C<system>, C<truncate>, C<unlink>, C<unshift>, C<values> =head1 OVERRIDING CORE FUNCTIONS To override a Perl built-in routine with your own version, you need to -import it at compile-time.
