in reply to Simple inheritance question
Perl has no idea it's suppose to call test as a method.
The only difference between a function and a method is how the sub is called, or rather, how it expects to be called.
test() # function Module::test() # function $obj->test() # virtual instance method $class->test() # static method
Non-virtual instance methods can be approximated using
test($obj) # From within the object that defines test(). -or- Class::test($obj) # From anywhere.
I say "approximate", since it's doesn't check inheritance.
And there's also this syntax:
$obj->Class::test() $class->Class::test() $obj->SUPER::test() $class->SUPER::test()
In this case, all of the following work:
sub eg { $_[0]->test($_[1]); } sub eg { One::test(@_); } sub eg { Two->test($_[1]); } sub eg { One->test($_[1]); }
Only the first really makes sense, though. And maybe the second one if you don't want test to be overridden by a child class of Two.
