Hello,
I'm aware that recently there has been discussion of R joining forces with
an algebra system in some way. Here is my $0.02.
I suggest linking R with Maxima (http://maxima.sf.net).
Maxima is written in Lisp. Maxima objects are pretty simple.
Maxima works on expressions, and almost every exp

Yes, optimization sometimes results in writes that are apparently
harmless and go away if optimization is removed.
It could be the bug you found (and glibc-2.3.5 had fixed) but it isn't in
