See the other answers for details and interesting stuff....  I just
wanted to clarify the point that you're not putting the colon before a
variable name, but before the string of which this is the equivalent
symbol.  You can even do:

   :"This is a symbol with whitespace"

or even the String#intern method:

   "So is this".intern
