Does it look *that* hard?

Yes, but I like the fact that Jtalk maps Smalltalk constructs
one-to-one with JS equivalents.

Switching to a fully externalized and decoupled message-send implementation like in ObjJ would allow DNU then as well. smalltalkMessageSend(someObject, 'doSomething:', anObject);

That's really interesting. Now, again, I would worry about the runtime
cost. Jtalk maps message sends to function calls. That's what makes
Jtalk fast.
