Almost. Rephrased just a bit:
"So you want to simplify usage of sealed ranges by forcing all structs

instead of eager copying?"
Yes :o).
Ok. And that means reference counting on the memory the struct allocates in
this(this) (and not on all uses of the struct itself)?
That is correct.
I should emphasize that this is in all likelihood going to be a
contentious point to C++ programmers used to eager copy semantics.
Reference counting is robust and often economical, but adds hoops to the
implementation - each method of the struct must redirect through the
refcounted handle and duplicate it if necessary etc.
I fear that it would be windfall for nitpickers, who in turn will
influence anyone who likes to worry.
