I don’t believe you can do exactly what you want here, as there are two parts:
1) getting `this` set properly. I believe you should be able to use
`CompileFunctionInContext()` to this effect, which is used to provide implicit
arguments to DOM onxxx=“script...” handlers. I believe you can then make `this`
whatever you want in that function. Return statements would still be legal, as
they are in DOM events, though.
2) completion value of the script. This is trickier, as the v8 API does not
expose a way to run the AST rewriter on arbitrary functions afaict. It may be
possible to introduce an API for this, if it’s important.
You might be able to take a third option, transforming the code with a custom
Babel plugin before passing it to v8 (at runtime), and providing the sourcemap
info along with it for debugging purposes.
