We're not talking about C compilers, which can cast any value at all
into pointers.  Languages designed for garbage collection are normally
type-safe and gc is a well-understood problem, though (like compilers)
the higher-performing ones are complicated.  But, nothing in principle
stops anyone from implementing Python with such methods.
