Sticky how? My proposal for object_event_add was V8; Luda believes he could write a faster JIT compiler with the more focused purpose of interpreting GML; problem is the experience factor. Luda's a talented individual; so's serp, and I like to think I am, but I'm not sure how we'd fare against the abilities of V8's team, even with a vastly simpler language. Really, I'm still quite open to suggestions on that matter. I will probably code something that generates the backend of an interpreter for games, and I know exactly how that will be done, but the front end is still completely subject to debate.
Sticky in how you parse EDL (you have to keep the whole script there the whole time), sticky in how you deal with dynamic code (V8 is sticky- it runs a completely separate language which means another [extremely simple] parser, you have to do more weird stuff to give it access to compiled types, etc.). Yes, these solutions work, but they're not the nicest to deal with. Compiling to C++ is a common enough solution, but when you actually add C++ to the language rather than adding the just concepts you want in a way that makes sense, you run into problems like this.
