=head1 NAME

use - Import several modules with a single use statement

=head1 SYNOPSIS

    # Use several modules in command line:
    % perl -Muse=CGI,DBI,PPI -e '...'

    # Import several modules at once
    use use qw[ strict warnings methods invoker ];

    # Pass options as array refs
    use use 'strict', 'warnings', 'HTTP::Status' => [':constants'];

    # Pass required versions after module names
    use use '5.12.0', 'HTTP::Status' => '6.00' => [':constants'];

    # ...or in your own module, importing on behalf of its caller:
    package MY::Macro;
    sub import {
        use use;
        local @_ = qw[ Module1 Module2 ];
        goto &use::use;
    }

=head1 DESCRIPTION

This module lets you import several modules at once.

This is almost the same as L<modules>, except that C<caller> is
properly set up so syntax-altering modules based on L<Devel::Declare>,
L<Filter::Simple> or L<Module::Compile> work correctly.

If a Perl version number larger than C<5.9.3> appears as the first argument,
then it's automatically expanded just like a regular C<use VERSION> statement.
For example, C<use use '5.12.0'> expands to C<use strict; use feature ':5.12'>.

=head1 SEE ALSO

L<perl5>, L<modules>
