[CodeCombat](http://codecombat.com/) is using it right now, and I see the issue. (I don't mind it at all; just adding an example of a site that uses it.)

It's MIT; I guess Xcode added that automatically. I'd be happy to have a patch to change it; thanks!

You could use the [Aether transpiler](https://github.com/codecombat/aether) for this. We use it in CodeCombat to expose only certain API properties of cloned objects and then restore the clones once user code...

Currently it seems the `list()` constructor is broken, probably by Esper? Just says `Dont do this yet.`

I'm going to guess that this is the same as the other bug with reusing list comprehension variable names: https://github.com/codecombat/aether/issues/133

Right now says `Dont do this yet.`

Now produces `Atempted to invoke bookmark for [Function]` @basicer

Probably related to #69.

Now it just does the assignment without complaining.

(CPU also spikes and often crashes the game.)
