NAME¶
Perl4::CoreLibs - libraries historically supplied with Perl 4
DESCRIPTION¶
This is a collection of ".pl" files that have historically been
bundled with the Perl core but are planned not to be so distributed with core
version 5.15 or later. Relying on their presence in the core distribution is
deprecated; they should be acquired from this CPAN distribution instead. From
core version 5.13, until their removal, it is planned that the core versions
of these libraries will emit a warning when loaded. The CPAN version will not
emit such a warning.
The entire Perl 4 approach to libraries was largely superseded in Perl 5.000 by
the system of module namespaces and ".pm" files. Most of the
libraries in this collection predate Perl 5.000, but a handful were first
introduced in that version. Functionally, most have been directly superseded
by modules in the Perl 5 style. These libraries should not be used by new
code. This collection exists to support old Perl programs that predates
satisfactory replacements.
Most of these libraries have not been substantially maintained in the course of
Perl 5 development. They are now very antiquated in style, making no use of
the language facilities introduced since Perl 4. They should therefore not be
used as programming examples.
