No, it is written in C++.

I don't think that speed would be the problem, but rather that
the "reflective calls" included in the virtual machine don't
give enough details for this application.

One problem of having this program load the system is that it would
distort the results we are interested in - the observer changes
the system being observed. That would be worse than any slowdown
in the other applications, in my opinion.

The problem is exactly the presence of some "holes" in Self 4.0's
reflection facilities. Nothing that would be hard to fix, though.
