Ruby :symbols understood - "A symbol is an object with a name"

Back in August
, I blogged about Ruby's symbols as I tried to get my head around what they really were. Jim Weirich made a post yesterday entitled 'Symbols Are Not Immutable Strings' which really helped solidify my understanding, his main two points being:

* Symbols are not immutable strings
* A symbol is an object with a name

Thanks Jim!
