Try this:

irb(main):001:0> a = []
=> []
irb(main):002:0> h = {}
=> {}
irb(main):003:0> h["one"] = "generic"
=> "generic"
irb(main):004:0> a[0] = h
=> {"one"=>"generic"}
irb(main):005:0> l = Marshal.load(Marshal.dump(a))
=> [{"one"=>"generic"}]
irb(main):006:0> l[0]["one"] = "local"
=> "local"
irb(main):007:0> a
=> [{"one"=>"generic"}]

(using globals if you absolutely must... but that's another story :-)
