Add robinhood hashing to structs.
...
This corrects changes in internal structure when values
were inserted in different orders (which was previously
incorrect.) Robinhood hashing should correct this by
making the internal structure of the hashtable invariant
of insertion order. This, in turn, allows naive and deterministic equality, comparison, and hashing of structs.

Change object to table type.
...
Tables are simpler and don't do inheritance via metatables. This means
object polymorphism will be done through a different mechanism rather
than Lua-like metatables. Perhaps smalltalk style messaging using
functions as objects, or lisp-like method dispatch.
