Reia (http://wiki.reia-lang.org/) certainly does something similar.  It
implements destructive assignment by transforming code into static single
assignment form.  All variables are versioned, and wherever variables are
destructively assigned the version number is incremented.  It works just
fine, aside from the normal caveats associated with destructive assignment.
