If a module looks as follows:
package Foo;
@EXPORT_OK = qw(get_foo);
sub new {
# constructer
}
sub get {
# for OO interface
}
sub get_foo {
# for procedural interface
}
1;
users may write as follows:
$o = Foo->new();
$o->get($key); # of cource, $value
$o->get_foo($key); # what's this?
If users choose OO interface, they shouldn't be able to call 'get_foo' method.
How can I solve this problem?

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).
