I've heard of requireJS, 
and it ships with r.js that apparently allow to transform commonJS require to a more async requireJS form. 

I've never used it though.

 I think that the commonJS
x = require('…')
is much more readable and understandable than the callback based one.

In the long run, I think that having a 'dev' flag would be great. 
Without the dev flag all the JS/css/coffescript/... would be minified and in one file. 
and if you want to introspect, you activate the dev flag and everything is unmignified and readable.

RequireJs Does allow that, which is a plus, even if it means adding a compile option to js.
