# 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\"}"
^
