|-----------------------------------------------------------------------|

HOOD enforces type consistency. Object-oriented languages are weakly
typed.

HOOD does not promote jumping into prototyping. Object-oriented
systems do not always mature out of prototyping.

HOOD has generics. Object orientation does not need generics.

Object orientation supports interactive modifications to the system
while it is being run, without relying on patches in machine code.
