Possible http status codes module for Elixir Phoenix Web Framework

# Would this be useful to Phoenix?
# In controllers, it'd be nice to be able to refer to status codes as atoms instead of integers.

koudelka / type_bully.exs
Created Mar 12, 2016
TypeBully is an (incomplete) toy module to force Elixir functions to respect their typespecs.
View type_bully.exs
# TypeBully forces functions to respect their typespecs by rewriting the function clauses to include proper guards.
# For example, the Wimp module below: cry/3 has typespecs, but no enforcing guards, normally, calling cry/3 would
# always match the first function clause, but TypeBully forces it to select the correct one based on its typespec.
# Without TypeBully:
# iex(1)> Wimp.cry("whaa")
