* Invokedynamic (like invokeinterface and invokevirtual) does not like calls with null as receiver, quitting the call right away with a NPE. But languages may allow for calls on null. That again means some kind of dummy receiver is required, if this is supposed to work. Wouldn't you just insert a null pointer check? That's surely going to be faster (if it's used) than the runtime taking a NullPointerException. And you don't want the runtime to have to trap for null when many languages don't need it.

Let's scrap that, outdated information on my side
