@boots How on earth could that have happened? Surely typeof isn't changing the _ var?
@boots Yeah. I'm pretty sure Ruby's IRB would behave some kinda similar way just with different particulars. I bet you'd end up at Class or Module instead of 'string'.
@boots Yeah:
irb(main):001:0> _ = "hi"
=> "hi"
irb(main):002:0> _
=> "hi"
irb(main):003:0> _.class
=> String
irb(main):004:0> _.class
=> Class
irb(main):005:0> _
=> Class
apparently the variable _ is replaced by whatever last output was
