I wanted to see if the +@ problem was fixed in 1.8.1 preview 3 but when I do 

  make install

I'm told that ruby's already installed and to use the -r option to reinstall. 
But make install dosn't seem to recognize the -r option. Is there something 
else I'm supposed to do?

As for +@: -@ works fine but +@ acts as if it doesn't exist unless one uses 
paraethesis.

  class Symbol
    def -@; "-#{self}"; end
    def +@; "+#{self}"; end
  end

  p -(:s)  # => "-s"
  p -:s    # => "-s"
  p +(:s)  # => "+s"
  p +:s    # => :s

Is there something about this that makes it unworkable? I hope not, since it's 
an important feature of a project of mine.
