Detailed Description

GblBox (reference-counted, opaque userdata), and related functions.

GblBox represents the most minimal type within the type system that is still runtime extensible and still offers everything typically required for an object to have bindings to another language.

A GblBox extends GblInstance with:

• Reference counting/shared pointer semantics
• Arbitrary userdata storage corresponding destructors
