I'm going to worry about CONST..CONST first.

Behaviour in 5.12 and earlier:
CONST..CONST returns something that can be modified, but that you're not
allowed to modify.

What the bug report requests and what the patch provides:
CONST..CONST returns something that can't modified.

What I'd like:
CONST..CONST to return something that you can modify.

Means of achieving this:
Remove the optimisation that computes the list at compile-time.

Any other faster means?
I don't know. You mentioned copy on write. Is there an existing mechanism
for that?
