=head1 NAME
builtins - Install all the new builtins from the C<builtin> namespace
=head1 VERSION
This document describes C<builtins> version 0.000001
=head1 SYNOPSIS
use v5.36; # Or later
use builtins; # Loads all new builtins into lexical scope
# So now we can write...
if (reftype($x) eq 'ARRAY' || blessed($x) {
say refaddr($x);
if (is_weak($x)) {
unweaken($x);
say ceil( refaddr(($x)) / floor($y) );
weaken($x);
say trim($description);
}
}
no builtins; # And now they're all gone!
=head1 DESCRIPTION
Perl 5.36 introduced numerous new built-in functions to the core.
Unfortunately, for backwards compatibility, none of them are
automatically available. And all of them are experimental
until Perl 5.40 (and then only if you actual specify C<use v5.40>).
Which means, if you want them all in Perl 5.36 or 5.38,
you have to preface your code with:
use experimental 'builtin';
use builtin qw(
ceil floor trim
true false is_bool
weaken unweaken is_weak
blessed refaddr reftype indexed
created_as_string created_as_number
);
Or you can use this module and get the same effect with just:
use builtins;
=head1 INTERFACE
None.
You simply use the module and it takes care of installing every available
C<builtin> built-in into the current lexical scope (just like a S<C<use builtin qw(...)>> would).
It also turns off the "experimental" warnings about each built-in it installs.
Or you write C<no builtins> and they are all removed.
=head1 DIAGNOSTICS
None.
=head1 CONFIGURATION AND ENVIRONMENT
C<builtins> requires no configuration files or environment variables.
=head1 DEPENDENCIES
C<builtins> requires Perl 5.36 or later.
It has no other dependencies.
=head1 INCOMPATIBILITIES
None reported.
It is specifically compatible with C<builtin>, so you can
still S<C<use builtins>> if you've already said S<C<use builtin>>
(and vice versa).
=head1 BUGS AND LIMITATIONS
No bugs have been reported.
Please report any bugs or feature requests to
C<bug-builtins@rt.cpan.org>, or through the web interface at
