UnManagedStruct is complicated by the need to handle nested structures. The need to consult nested structures for their shape, support for multi-element keyed lookup, etc...
These are a higher level concepts than "view this buffer as a collection of these datatypes", and as such do not belong in UnManagedStruct. Therefore the following aspects of unmanagedstruct are deprecated:
* remembering structure of nested structured elements. These will now be treated as {{{ void * }}} or {{{ void (*)(void) }}} as appropriate
* multi-level keyed access
