I wish the following code would parse and run: ```ruby # shareable_constant_value: literal class Foo < RuntimeError end # Similar code, but does not parse: Bar = Class.new(RuntimeError) # => unshareable expression Baz = Ractor.make_shareable(anything_here) # => unshareable expression Qux = Set[1, 2, 3].freeze # => unshareable expression ``` Could we instead raise some sort of RuntimeError when an assignment is made that is not shareable? -- https://bugs.ruby-lang.org/ Unsubscribe:
