#5. The __deriving__/3 Macro
Elixir Tip of the Day #5: Within an Any implementation of a protocol, define the `__deriving__/3` macro to accept options. This allows configurable fallback behaviors rather than just one implementation. Modules like Jason and Inspect use this in great ways#MyElixirStatus pic.twitter.com/0pxKsF858j
