If true, and you're confident enough in this that you think we'd have no trouble finding an expert witness (such as a professor of computer science) to testify to this effect, then in the United States, this would be a serious blow to such code being copyrightable in the first place. Under U.S. copyright law, a work has to be "expressive" and "original" to enjoy copyright protection. If there's only one way, or an extremely narrow range of ways to accomplish something, copyright does not attach. For example, in the U.S., you cannot copyright your filled-out income tax return. Of course, I speak of the U.S. only. In other jurisdictions, it may be possible to assert a copyright on, for instance, the sequence of prime numbers smaller than 100, in increasing order. Whether we need to be worried about other jurisdictions is a question I will leave to others, as I'm only willing to play armchair lawyer with respect to U.S. law. > Anything you may do, these calls are needed, you could add some noop > calls in between, or some random stuff, but i doubt that this will be > more than smoke and mirrors.
