Can we extract the babel options to a shared variable?

Can we refactor this to the following?

I don't think we should add a config for this if we don't need to...

Why do we need this? If it is just for the testing, can we tweak it to just mock console?

I'm not entirely sure what you're getting at, but I simplified things a bit and changed the arguments to support setting loader.deprecationLogger = Ember.deprecate if we wanted. What do you think?

Should probably note in the deprecation message that this behavior can be turned off via loader.makeDefaultExport now.
…lt` exports If a module does not define a default export, loader.js assigns `exports.default = exports` for compatibility with modules that don't use `_interopRequireDefault` from babel6. Mutating exports is unexpected behavior and causes difficult-to-diagnose [bugs][1]. We should remove `makeDefaultExport` in version 5.0. This update * adds a deprecation warning in preparation for removing `makeDefaultExport`. * adds a debug build with the deprecation enabled. Addresses ember-cli#114 [1]:mike-north/ember-lodash#104
This change adds a `loader.debug` option to Ember CLI builds. It defaults to true for development and test builds. When true, it prepends loader.debug.js instead of loader.js to the application's vendor.js.

@trentmwillis Good catch. I added instructions for disabling makeDefaultExport in the deprecation message. |
