Ractor.shareable_lambda

[T] () { (?) [self: nil] -> T } -> ^(?) [self: nil] -> T

[T, S] (self: S) { (?) [self: S] -> T } -> ^(?) [self: S] -> T

Ractor.shareable_lambda(self: nil){} → shareable lambda

# File tmp/rubies/ruby-4.1.0-preview1/ractor.rb, line 718
def self.shareable_lambda self: nil
  Primitive.attr! :use_block

  Primitive.rb_builtin_shareable_lambda(Primitive.local_self!)
end

Same as Ractor.shareable_proc, but returns a lambda Proc.
