Well, in most cases the length function should be marked const 
because it usually doesn't modify the struct in any way. But this 
isn't possible if you have a composed range because you don't 
know if the data/range underneath has a const length. This also 
applies to the front function in a lot of cases. And because of 
these two cases I think adding const to a lot of the member 
functions could result in slightly better code-gen.
