elixir - Implementing a protocol by delegating to existing functions -

-

i'm learning elixir modeling board game, , have code:

defprotocol board   def can_handle_move(self)   def handle_move(self, move) end  defimpl board, for: list   def can_handle_move(self), do: enum.empty?(self)   def handle_move(self, move), do: list.delete(self, move) end

the implementation looks more complicated is. actually, can_handle_move enum.empty? , handle_move list.delete. elixir have way of expressing this? like:

defimpl board, for: list   def can_handle_move = &enum.empty?/1   def handle_move = &list.delete/2 end

...which doesn't compile. i've tried without defs.

try kernel#defdelegate/2 it.

defimpl board, for: list   defdelegate can_handle_move(self), to: enum, as: :empty?   defdelegate handle_move(self, move), to: list, as: :delete end
