Subject: [ruby-talk:9770] obj.freeze?

obj.freeze is not working as I expected it.
Can someone explain the following code.
(ruby 1.6.2 (2000-12-25) [sparc-solaris2.6]

---begin code---
fred = "fred"
puts fred
fred.freeze
puts fred.frozen?
fred = "flintstone"
puts fred

a = [ "a", "b", "c"]
a.freeze
a << "z"
---end code---

---begin output---
fred
true
flintstone
./module.rb:36:in `<<': can't modify frozen array (TypeError)
        from ./module.rb:36
---end output---

Why do I not get the same error with fred?
