So, is this a limitation with inout, part of its design, or am I misunderstaning something more fundamental?
It's fundamental: inout makes sense for function attributes only and can't be used as a template parameter or struct/class field (what map attempts). Opaque template parameters would solve the issue and can be also used for other purposes, but on the first sight they seem like a task of galactic scale, hence nonviable.
