On a side note, I do believe that short programs or functions should be copyright free by law. Or we as a community need to create a better bsd, a cc0 for everything. Almost everything is nontrivial, and almost everything is copyrighted, at least with the pressure to name the original author (BSD, GPL, other major permissive licenses). Say you want to use a library, then you check for examples in the documentation, now you have to denote somewhere that the example is from the documentation (best if you put it in the source code, so you don't lure other people to copy what you copied and refer you as the author). It is a major PITA at least for me.
