IIRC OO is a design pattern. Just happens many langs support it directly.

Others have pointed out adding bits to identify instruction types eats into your instruction length, so let's go stupid big time: what if you had the instructions as described here, without any instruction length being part of the inst

Why would you need a 64 bit instruction; what kinds of things are going to be used for it? What does 'rare' mean here, does it mean rare in execution, or rarely appears in code? (The difference being that something might only appe

I need to do some more checking, but you are right. The original relational algebra was a subset of first-order predicate logic. Adding recursion I believe just gave it parity with 1st order PL, so fulsome apologies and thanks for pointin

Fair Q, I may be confusing relational and predicate calculus. Will check and get back. Apologies in advance if I'm wrong.

> Relational algebra is not Turing complete. yes it is > SQL gets Turing completeness by means of various additions/alterations. Sigh. No. SQL was a subset of relational until recursive CTEs were included to round it off properly

I did say 'typically'! Yes, agreed, but it should rarely need help. Also hints are oh so often jammed in by newbies. I strongly get the impression use of hints is inversely correlated with experience/knowledge.
