If translate() is intended as a hook for transpilation, it will lead to fragmentation.
I don't have crystal ball but I am concerned about 'transpilation' as a feature in the loader api.
I should probably add:
module Crypto from "classes/crypto/Crypto.asm.js" (compiled from c++)
"Our goal is to make the open web a compelling virtual machine, a target for compiling other languages and platforms."
Is there some consensus that the web "needs typed language foo"?
Don't get me wrong, asm.js is really clever from a technical standpoint.
I'm finding it difficult to not be worried about the non-technical implications.

Sure but that's a bit of a stretch, XMLHttpRequest was initially designed to load XML and inline script tags are quite inconvenient for large amounts of code.
By design in this case, source code transformation is encouraged either by programmers or by the browser.
