Unlikely, the same commit added it all, I can only assume the offline version behaves similarly (I haven't tested).

The compiling seems very inconsistent and fragile:

* it won't convert at all if a function literal is returned or assigned to a variable (but it will if the function literal is passed to an other function or for IIFE)

* it will generate an incorrect conversion in case the `this` is deref'd for a method call or (directly or indirectly) passed to an other function: these are OK (will not convert)

    (function () { this; })();
    (function () { this.foo; })();
    (function () { this.bar + 1; })();

but these are not ok (will convert to incorrect code):

    (function () { this.foo(); })();
    (function () { foo(this); })();
    (function () { foo(this.bar); })();
