Thanks the example from Class::Tables is interesting. :)

And I now understand goto &$method_ref seems to follow the @ISA chain.

It doesn't, this was my brain fart. =)

It's the ->can() which already returned the correct code_ref after following the inheritance chain

And that's highlighting the difference to Class::Table, $func is a string not a ref.

Additionally goto &field is not a dynamic call, it will always call the same sub field in the same package.

Though ->field could be called as a method form other points, since it expects $self as first argument.
