Disable usage of Ractor.make_shareable on Ruby 3.0 as it's broken on Ruby 3.0.2.

[ioquatix]

The following test code demonstrates the problem:

#!/usr/bin/env ruby

class Object
	if const_defined?(:Ractor)
		def self.define_immutable_method(name, &block)
			block = Ractor.make_shareable(block)
			self.define_method(name, &block)
		end
	else
		def self.define_immutable_method(name, &block)
			define_method(name, &block)
		end
	end
	
	def self.[] **levels
		klass = Class.new(self)
		
		klass.instance_exec do
			levels.each do |name, level|
				define_immutable_method(name) do
					puts severity: name, level: level
				end
			end
		end
		
		return klass
	end
end

Filter = Object[info: 0, debug: 2]

filter = Filter.new

filter.info
filter.debug
