That is basically the core insight behind julia. The really performance sensitive parts of your application are already static just by the nature of that code, so we can extract that static information to make it really fast. We can also make use of the same static information for static error messages or static compilation and get the best of both world (dynamic during development, static when you're done), but the tooling for that is a bit less developed at the moment.
