Re: [AD] Allegro JavaScript port using Emscripten (First version complete)

[Max Savenkov <max.savenkov@xxxxxxxxxx>]

OK, I have looked into using coroutines to allow create 
main-addon-powered abstraction. It seems to be possible, but 
unfortunately coroutines currently only available in Firefox and Chrome 
(with Experimental JavaScript flag enabled: 
http://kangax.github.io/compat-table/es6/, look for Generators (yield) 
). No other browser support it, and even in Chrome, users would have to 
dig around settings to make such code work. So, no, I believe that we 
can't presently use coroutines to implement endless loops with yield. 
The trouble is, Generators (and the whole ECMAScript 6 standard isn't 
finalized yet, so relying on it would be a bad idea, especially if my 
port is to be merged into the main library. Maybe in experimental, 
separate port, it may be possible to use such a feature.

So, for now I'm stuck. I can see no other way to avoid having frame 
function.
