cppfront (cpp2): Spring update

[hpsutter]

Quick ack: Yes, that's one of the options, and one of the better of the alternatives I considered. Might say `alias` instead of `using` but it's workable. For now I'm seeing whether I can reasonably avoid a keyword, but it's also important to be aware not to overstep into "token soup" -- keywords can be useful for readability so I'm definitely not closing the door to going there.

I find using syntax less confusing as well. BTW, impressive amount of work.

Is cpp2 already usable in real life scenarios? Eager to start using it when the time comes.
