Overview

  • Single splat * converts nil to empty array.
  • Double splat ** raises on nil.
  • Umpersand & converts nil to nil.

The following middleware converts env[:kwargs] to a hash. This way stack.call(*env[:args], **env[:kwargs], &env[:block]) won't fail even if a user passes nil as kwargs.
