Comment (by neilgroves):

 I think I have a solution. I'm starting prototypes and will attempt to
 apply this to some large codebases to ensure that backward compatibility
 is maximised.

 I believe we can alter the return types to have an additional template
 paramter or N template parameters (to be decided) that describe some
 additional range category decoration. These will be used to determine if
 the range should be held / moved. By using a default template paramter(s)
 for these new parameters we can maintain old behaviour for old code while
 allowing new code to work in the manner requested. I believe that this
 fits nicely with other new features that I intend to release.
