##
# - 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`.
