Re^3: New Module Announcement: Object::InsideOut

[diotalevi]

If you treat the scalar as an opaque object, store nothing inside it and use overload::StrVal as the key instead, you can allow ${} to be overloaded as well. Data::Postponed uses blessed scalars as the object and allows anything what so ever to be overloaded.

Then you are back to the same performance problems encountered with Class::Std, namely you have to calculate the object ID on every access.

It is an engineering trade-off that I feel is more than justified. By storing the object ID in the object's scalar, the only thing you give up is the capability to overload the ${} operator.

And the ability to subclass foreign code without knowing about its implementation.

[You also give up] the ability to subclass foreign code without knowing about its implementation.

As of v1.18, Object::InsideOut supports inheritance (i.e., sub-classing) of non-inside-out object classes.
