closedirb: Really weird behavior for x = "#{x\"}" (ex: irb(main:009:-4))
Description
Our journey starts off rather simple:¶
irb(main):001:0> x = "#{x}"
=> ""
Okay, makes sense.¶
irb(main):002:0> x = "#{x"}"
irb(main):003:0"
Hmm...Still in a string? That's weird.¶
irb(main):003:0" "
irb(main):004:0>
Things seem back to normal but...¶
irb(main):004:0> x
Nothing? But x is defined!¶
irb(main):005:0>
Nothing? Hmm...¶
irb(main):005:0> end
irb(main):006:-1> end
Uhh...I don't think that's supposed to do that.¶
irb(main):007:-2> end
irb(main):008:-3> end
irb(main):009:-4>
...I'm afraid to go deeper.¶
Get me out of here!¶
irb(main):009:-4> quit
irb(main):010:-4>
O.O¶
irb(main):010:-4> ^C
irb(main):010:0>
...Can I go now?¶
irb(main):010:0> quit
Success!¶
Additionally, if I put this in a file:¶
x = "#{x"}"
I get two syntax errors (ruby 1.9.3):¶
test.rb:1: syntax error, unexpected $undefined, expecting '}'
x = "#{x"}"
^
test.rb:1: syntax error, unexpected $end, expecting '}'
x = "#{x"}"
^
