In the sense that it's a third party module, yes. Not in the sense of how
it hooks into the runtime. The intention would be that users explicitly run
their code in a JIT compiled environment, e.g. their template processing or
math code. The runtime wouldn't switch to a JIT compiler automatically for
"normal" code.

I mean, that could still become a feature at some point, but I find a
decorator or an exec-like interface quite acceptable, as long as it fails
loudly with "can't do that" if the JIT compiler doesn't support a specific
language feature.
