Subject: different handling of local variables and instance variables when undefined

Hello,
I somehow stumbled over a, how I think, strange behavior. When I try to
handle a undefined variable in irb I get something like that:

irb(main):001:0> !blubb
NameError: undefined local variable or method `blubb' for main:Object
        from (irb):1

But when I do the same with a undefined instance variable I get:
irb(main):002:0> !@blubb
=> true

I think that is somehow strange. Because of that I have overseen a
mispelling in the instance variable name. Is that the wanted behavior?

Tammo
