Can someone help me out with this, I can't put the string 'a\b\c' in
the variable str, which is strange, because I am working with the
PickAxe book, and this what should work (page 71, 2nd ed.)

the two before seem to work, but the example in the book, 'a\b\c' seems not.
This a bug? How come irb does not seem to understand the last quote?

irb(main):021:0> str = 'a\b\c '
=> "a\\b\\c "
irb(main):022:0> str = 'a\bc'
=> "a\\bc"
irb(main):023:0> str = 'a\b\c'
irb(main):024:0'
irb(main):025:0' '
SyntaxError: compile error
(irb):25: unterminated string meets end of file
        from (irb):25
        from :0


I'm very curious,  :-)
