.iex.exs error behaviour

[ConnorRigby]

Environment

• Elixir & Erlang/OTP versions (elixir --version): Elixir 1.7.3 (compiled with Erlang/OTP 21)
• Operating system: Linux

Current behavior

Loading .iex.exs with compile or runtime errors currently halts the system. This is currently intentional as seen here.

Expected behavior

I'd like to discuss if this is the best behaviour. For Nerves (and i suspect any other Distillyery based release system) this will cause the vm boot to fail. Would there be interest in changing this to either just not halt the system, or have the behaviour configurable via the command line or something?

@ConnorRigby agreed. Can you please send a PR that removes the halting and have only the logging and add a test as well?

[ConnorRigby]

Happy too. Thanks!

Closing in favor of #8619.
