GSOC: First update

GSOC: First update

[Ian Price]

Hi,

As some of you will know, I am implementing a guile->js backend as
part of Google Summer of Code. This is a small update so that those of
you who do hang out on the guile irc channel can see some of the
(small) progress.

A temporary git branch is available at
https://gitlab.com/ijp/guile/commits/compile-to-js

I'm not going to list all the reasons you shouldn't use this code yet,
suffice to say you shouldn't. It's so far before alpha it's not even
funny.

That said, code you can compile today includes multiple values [1],
mutual recursion [2] and using call/cc to escape early from a
loop [3].

1. scheme: http://shift-reset.com/pastes/merge.html
   js:     http://shift-reset.com/pastes/merge-js.html

2. scheme: http://shift-reset.com/pastes/even.html
   js:     http://shift-reset.com/pastes/even-js.html

3. scheme: http://shift-reset.com/pastes/product.html
   js:     http://shift-reset.com/pastes/product-js.html

To make the examples self-contained and runnable in node.js, I
included the code from module/language/js-il/runtime.js, assigned the
result to a var and call console.log, and beautified it with uglifyjs
for good measure. The actual output of "guild compile --to=javascript
foo.scm" can be found between the comments.

nice job!
I've read the code very quickly, my understand is to convert CPS to
plain JS code directly, right?
Do you have a plan to generate it according to asm.js spec?

Excellent, thanks for the update!
