A package is just a namespace identified by a string.
package Test::One;
sub hello{
my $var = shift;
print "Hello: $var\n";
}
1;
package Test::Two;
sub hello{
my $var = shift;
print "Hello: $var\n";
}
1;
package main;
use strict;
use warnings;
use Data::Dumper;
my @pkgs = qw( One Two );
foreach my $pkg ( @pkgs ) {
"Test::$pkg"->hello();
}
This is one step toward full-fledged classes and objects, which may be a better solution in the longrun: perlobj.
If you can't plan on passing the package name as the first parameter (which is what the Class->method() notation does), then you have to construct the fully qualified sub name, which means symbolic references and some ugly syntax:
foreach my $pkg ( @pkgs ) {
no strict 'refs';
&{'Test::' . $pkg . '::hello'}($pkg);
}
Update: Good job on figuring out the symbolic ref syntax on your own. Looks like we both came up with the same.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
