According to The Well Grounded Rubyist:

Ruby allows a special form of symbol representation in the hash-key position, with the colon after the symbol instead of before it and the hash separator arrow removed. In other words, this:

hash = { :name => "David", :age => 49 }

can also be written like this:

hash = { name: David, age: 49 }

I have tried the preceding code in ruby 1.8.7 and 1.9.2 - It is not working. What am I doing wrong?
