Re: This is a tough one...
Or another way of looking at it.
Developer A said "let there be a language where statement A does B, statement C does D etc"
Developer A happened to then implement that in code, Separately developer B implemented the same thing in different code.
If developer A is allowed to claim that all implementations of their language are copyright then Dennis Richie is going to be very rich - and Oracle are going to have a real problem finding a C compiler to build their database product.
