This will however not show up inherited methods. Which can be the desired behaviour in certain cases of course.

use strict;
use warnings;

if (exists &FOOBAZ::bar) {
    print "bar exists in foo\n";
}
if (FOOBAZ->can("bar")) {
    print "FOOBAZ can do bar\n";
}

package FOO;

sub bar {
}

package FOOBAZ;
use base("FOO");

Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it. -- Brian W. Kernighan
