     Actually, if you &-ize it on the way in you should  be fine in 1.8
(at least, it works transparently for me).

Oops.  Sorry, it's from my personal bag o'tricks (another ported
lisp-ism):

class Symbol
    @@unique_sym_counter = 0
    def Symbol.unique(prefix="gloop")
        prefix = 
          prefix.to_s.
          gsub(/\+/,'_plus_').
          gsub(/\*/,'_times_').
          gsub(/-/,'_minus_').
          gsub(/\//,'_div_').
          gsub(/\!/,'_bang_')
        return ("#{prefix.to_s}__#{@@unique_sym_counter += 1}").intern
        end
    end

So, I'm curious right back: why the aversion to aliasing?
