Changing all directory import statements to explicitly import index.js

[jpray]

Hi, I love this project! Would you all consider accepting a PR that changed all directory import statements from import './foo' to import './foo/index.js'? I know node and webpack support the current style but other module loaders like systemjs don't. Thanks for considering this.

MDC Web only intends to support the formats listed in importing-js.md.
However we encourage you to ask SystemJS to add support for the import './foo' syntax!

Bummer, I mean, the syntax is still ES2015. The issue is just that having /index.js be implicit isn't part of any standard loader spec that I know of. So a module loader that sticks strictly to a standard like whatwg loader can't support this... and this makes sense because it would be bad for a browser to make multiple calls to the server seeing if foo.js or foo/index.js existed.

It wouldn't be a breaking change. I'd include tests in the PR. :)

Ok...you've convinced us. :) However we still think that the import {...} from 'path/to/index' (without the .js extension) makes most sense, as per http://2ality.com/2014/09/es6-modules-final.html. Adding @kfranqueiro and @acdvorak to this thread in case they want to speak more on it.

Feel free to submit a pull request that:

• changes all directory imports from import './foo' to import './foo/index'

Sweet! I'm fine with omitting the '.js' part. I've submitted #2111 for this issue.
