By doing static analysis, you can determine a lots of things that can
be compiled. The difference with a static language, are for the corner
cases, for example if you introduce a new method to a class, or load
new code into the VM, .... In these cases, you need a fallback.
Typically, the runtime includes an slower path for these cases, like
an interpreter, or an AOT compiler.
