This is not directly related to the paper I mention later. I was talking
about optimizing bytecode vs. compiler optimizations. I know of no
interpreter doing elaborate static byte-code optimization.

I'm glad it works for you. For the record: they consider interpreters
for Python, Javascript and CLI, on a fairly broad set of benchmarks. And
they also evaluate (through simulation) branch-predictors that may (or
may not) be included in more recent architectures.
