You mean [Monday, Tuesday ... Sunday, Monday] ?

Actually not. No repetitions.

That seems like a very bad idea. '..' normally means 'inclusive', breaking those semantics would be a very weird thing to do, and breaks the principle of least surprise.

Good point. When I think about it [Monday .. Monday] should probably not return the same as [Tuesday .. Monday]. (Ofcourse a new class would not permit the use of the [X .. Y] notation if not added to the language somehow.)
