def call_proc(proc, *params)
  # The parameters array for a lambda created from a symbol (&:foo) differs
  # from explictly defined procs/lambdas, so we can't deduce the number of
  # parameters from the array length (and differs between Ruby 2.x and 3).
  # In the case of negative arity -- unlimited/unknown argument count --
  # just send the object to act as the method receiver.
