No, there's no interpreter. It would be very slow (somebody at ETH
wrote a Self interpreter in Oberon, and it came out to be at least 100
times slower than C).

It's in the VM.

I'm not sure about the numbers in benchamrks.self, they're probably PP
2.4. For a new paper (October IEEE Computer) we measured 4.0 which
was faster on some benchmarks (if I remember correctly), but not
spectacularly so (10-20%).
