For a safe and fast Erlang SSL server, there's a few 
configuration values you might want by default:

    [{ciphers, CipherList},      % see below
     {honor_cipher_order, true}, % pick the server-defined order of ciphers
     {secure_renegotiate, true}, % prevent renegotiation hijacks
     {client_renegotiation, false}, % prevent clients DoSing w/ renegs
     {versions, ['tlsv1.2', 'tlsv1.1']}, % add tlsv1 if you must

# You will need fswatch installed (available in homebrew and friends)
# The command below will run tests and wait until fswatch writes something.
# The --stale flag will only run stale entries, it requires Elixir v1.3.

Flaws in unquote fragments

A couple weeks ago, we have pushed support to unquote fragments:

Enum.each [a: 1, b: 2], fn { k, v } ->
  def map(unquote(k)), do: unquote(v)
end

Although it provide a nice way to dynamically define functions, after discussing with developers and extending Elixir to rely more on it, some flaws became aparent.
