If you mean Oforth uses aligned pointers and steal one or two bits for
tags, that's a very common technique and works well. The SPARC
processor even had hardware support for that, which nobody seems to have
used. If you mean the heap uses different regions for different object
types and figures out the type of a pointed-to object from its address,
that's another venerable technique called BIBOP ("big bag of pages")
though it was used mostly in older, smaller systems.
