The root of the problem might be:
irb(main):001:0> a
NameError: undefined local variable or method `a' for
#<Object:0x258d558>
        from (irb):1
irb(main):002:0> @a
nil
irb(main):003:0> @@a
NameError: uninitialized class variable @@a in Object
        from (irb):3


But then why:
irb(main):008:0> b||true
NameError: undefined local variable or method `b' for
#<Object:0x258d558>
        from (irb):8
irb(main):009:0> b||=true


It seems like ||= has some extra hacking. Any ideas?

Using ruby-1.7.4 under WinME, downloaded from PragmaticProgrammer
What about the above with the CVS version?

ps: When will be a newer installer available under windows?
