That's not necessarily a good idea. What if the element type
can't even be used when it's const? inout might work in that
case, but in general, you have to be _very_ careful with
slapping const on generic code.

The return type was const from the beginning; see also

Well, it won't work in the general case to have front returning a
const value. There are too many types that are completely
unusable when const. It may be that you don't want it returning
by ref if it's not const, but const is simply way too restrictive
to be required.
