Since structs were supported, this rationale does not work.

Remember that I wrote successful C and C++ compilers for 16 bit 8086 machines, 
and programmed on it for a decade. I know about those instructions, and I'm 
familiar with the tradeoffs. It's not worth it.

Besides, C was designed for the PDP-11, which had no such instructions.
