Learn your grammar. cpu's is the singular posesive. To prove his point
all he has to do is give one example. It is a bit much to ask him to
give examples for a majority of the CPU's available on the market.

He did not claim that CPU's were designed for Lisp. He claimed that they
were not exclusively designed for C. I would not be surprised to find
that there are instructions that Cobol or Ada, but not C, could use, or
instructions that an OS could use which has no C equivalent. And he did
not claim that any additional instructions that other languages might
use, and C could not use, involved types, other things could involve
garbage collecting, certain forms of exception handling, etc.
As a side point, does anyone know if the newer "Java" chips have
instructions that check types?
