An even better example is puts xyz # should raise name error if false xyz = 1 end puts xyz #=> nil The thing is that params isn't initially a local variable - it's a method that then gets shadowed by a local variable, i.e. def xyz "moo" end puts xyz.inspect #=> 'moo' if false xyz = 1 end puts xyz.inspect #=> nil Fred > puts x > > This code outputs 3, not nil.
