"In particular, the laws stress that it is a programmer’s expression of some functionality that may be protected by copyright, and not the functionality itself. If code embodies the only way (or one of very few ways) to express its underlying functionality, that code will be considered unoriginal because the expression is inseparable from the functionality. Similarly, if a program’s expression is dictated entirely by practical or technical considerations, or other external constraints, it will also be considered unoriginal."
Sounds like a case that at least some snippets aren't copyrightable.
