# Protocol version of the Enumerable module, that actually checks, if #each
# was implemented by the including (conforming) class.
Enumerating = Protocol do
  # Iterate over each element of this Enumerating class and pass it to the
  # _block_. Because protocol cannot determine if a block is expected from a
  # C-function, I left it out of the specification for now.
