My GSoC weekly report

[Jonathan "Duke" Leto]

Howdy,

Yes, daily reports would be appreciated!

Generating "vim folds" is a nice trick. Clever!

I am not sure if you have considered it, but will your code be able to
easily target JavaScript OR the low-level subset of JS called "asm.js"
[0] ? It is gaining wide support and is backed by Mozilla.

Asm.js is essentially a simple flavor of JavaScript that JIT engines
can optimize more efficiently than normal JavaScript.
