Derived from #21011.

Even with prism:

# shareable_constant_value: experimental_everything
A, = ""
p A.frozen? #=> false

This A should be frozen?

Furthermore:

# shareable_constant_value: experimental_everything
A, a = "A", "a"
p A.frozen? #=> false
p a.frozen? #=> false

Should only A be frozen but not a?
Or massign including a constant can freeze everything?

Yeah we found this when we were building prism (https://bugs.ruby-lang.org/issues/20340). I don't know what the expected behavior here is.

• Is duplicate of Bug #20340: Ractor comments not applying to constant targets added

[matz (Yukihiro Matsumoto)]

In my opinion, only constant assignment should make assignee shareable.

Based on https://bugs.ruby-lang.org/issues/21016#note-4, I think this is the expected behavior.
