The if $obj is a MyClass object (with no superclasses), the call to $obj->foo is equivalent to MyClass::foo($obj).

Note that this has nothing to do with the package Plugin -- so why does ego->{name} in MyClass::foo go to a Plugin storage slot? Because the foo function was first compiled in Plugin.

Whether you think it's good design or not, importing functions from some other .pm file and using them as methods is a common practice.

Of course, 'regular' inside-out classes wouldn't allow a plugin to attempt this -- the imported function wouldn't be able to access the lexical hash storing the property and it wouldn't compile. A plugin would be forced to use the accessor API.

What Alter does isn't 'wrong' per se, it's just sufficiently different to what people are used to that it's another potential source of unexpected bugs.

Put differently, it's yet another object paradigm for Perl.
