Subject: What about {:a => "a", :b => "b"} argument

Hi

I'm doing some gnome/ruby stuff and I wonder how instance method's 
argument like {:a => "a", :b => "b"} can be used. Such argument are 
used, for example, in Gnome::CanvasLine.new and seems to set instance 
variables.

I didn't succeed to use such hash argument. The only way I got is by 
using {:@a => "a", :@b => "b"} with a code like

Class Foo
   def set(hash)
     hash.each {|k,v| self.instance_variable_set(k,v)}
   end
end

Can you explain me how {:a => "a", :b => "b"} should be handled?

Thanks

Nico
