I can lay out all the issues with this if you want me to, but after my
previous email I don't think I have to. I'm just wondering why you say it
doesn't need to inspect the underlying source code. That's what
`code_context` is and that's obviously the only place where a string like
`'M('` could be found, unless you want to uncompile bytecode (which is not
impossible either, but it's an additional mess).
