Yes, the whole "this" system in JS is pretty insane. Naturally Nulan solves this by requiring you to explicitly pass in the object. This also gives you the "call" and "apply" behavior of JS for free, in an orthogonal way.
P.S. The JS version of Nulan is coming along quite nicely. 25 working macros and 10 semi-working macros. It can handle a ton of stuff already, but it still has a long way to go!
