Yeah. I probably should have been clearer about it in my original post. They 
have a length property, but as for as ranges are concerned, they don't. 
hasLength is the mechanism that that's checked with though, so perhaps I 
should use that when explaining. The same goes for isRandomAccessRange and 
isSliceable. They're false for arrays of char and wchar in spite of the fact 
that they're arrays and thus have random access and are sliceable, because 
they're random access and sliceable only on code units, not code points.
