Now that dojo/core#270 has landed, this PR can be updated to use the useDefault mapper, correct?

[lzhoucs]

I think so too, Matt! Will do it shortly!

@mwistrand @lzhoucs I didn't realize this PR existed... 😄 I have https://github.com/dojo/i18n/pull/56 to update load to use the new request API from dojo/core. If you can use anything from there, great, otherwise just toss it.

[lzhoucs]

@rorticus thanks! This one is simply updating the load usage. It is not touching request.

This one is very minor anyways. Maybe we can just close it and add those lines whenever we clean up the code in the future.
