I previously brought this up with the OTP team and was reminded that this
also affects config files, .app files, and also setting env vars from the
command line, with the point being that there could well be unintended side
effects of such a change. Some Riak code used to take advantage of what
you've described, but after the discussion we modified our code to honor
the type spec.
