Thanks for the explanations of the internals.

I understand about the 'redefining log' problem in the interpreter,
but I wasn't aware of the NAMED counter.  In both cases, beyond static
analysis, dynamic Java compilers do a pretty good job, but I don't
know if Java bytecodes are suitable for R, and if they are not, it
would be a lot of work to duplicate the analysis for an R compiler.
