Suppose I want to do the following:

use MyModule 'foo' => 'bar', qw/do_something do_something_else/;
[download]

So I want to:

• Set the global configuration value foo to 'bar'
• import the class methods do_something and do_something_else into my namespace

Assume for this example that I don't need to be able to specify the value for foo at runtime.

I can define MyModule like so:

package MyModule;

our @EXPORT_OK = qw/do_something do_something_else/;

my $FOO;
sub import {
    my ($class, %config) = @_;
    $FOO = $config{'foo'};
}

sub do_something {
    if ($FOO eq 'foo') {
        # do something here
    }
    else {
        # do something else
    }
}

sub do_something_else {
    if ($FOO eq 'foo') {
        # do something else here
    }
    else {
        # do something other than else
    }
}

1;
[download]

But how would I then pass ('do_something', 'do_something_else') to Exporter?
