Everyone else hated this idea, but what do you think of:
- T& .value() returns a reference to the value, non-destructive.
- T .get() returns the value by value, destructive.
I personally like this plan, but no one agrees with me. I do agree that
the availability of copy construction muddies clarity of usage very
significantly - a separate move only type implementing .get()
destructively from one implementing .value() non-destructively looks
