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)
