Luca,

The return value from $a->can(test) checks if there is a method called 'test' within the class or object. If it does then a reference to the sub is returned, else undef is returned.

This can be used to conditionally invoke a method:

$dead->dance if $dead->can("dance");

Update: as derby mentions check the documentation :)
