Well, I only want it for read-only access so it shouldn't be
too dangerous.  What's so bad about a convenience function 
like the following?

  def printvar(varname)
    puts "varname = #{get_value_of_var_from_caller(varname)}"
  end

#get_value_of_var_from_caller would be implemented in terms of
the ideas in [ruby-talk:22963].
