Is it time to consider that one zval isn't the answer to all puzzles?
Perhaps a light and heavy weight zval make sense here, where the light
zval makes assumptions about local scope, not reentrant/threadsafe, while
a heavier zval could be used for objects and meta objects with general
functionality including thread safety, redundancy, validity and scope??
