[erlang-questions] erl_tidy and specs

[Gleb Peregud]

The fact that Go team created and popularized "go fmt" from the
very-very beginning was an awesome move! I would really like to be
able to read the code which is always sanely and consistently
formatted. If someone had time to improve erl_tidy and OTP team would
promote it more, I would so very happy.
