Frankly I'd far rather the language dealt with this sort of thing itself so users never need to think about it, but it doesn't, so whatcha going to do? So, other than the embarrassing syntax, that one I'm not too bothered about. If nothing else it serves to make users aware that such an issue even exists.
But is a StandardLib the place to make the point? If you want a lib that people are going to use, I think you need to concentrate on what you think they *will* use, not what you think they should, and try to keep it compact enough that people don't just give up wading through comments. And I think that needs a touch of the Jobsian approach, throwing out (well, moving elsewhere) what doesn't answer a common problem. Education is mission creep too, in this instance.
