Thanks! I was recently thinking that I take symbols for granted and needed to dig a little deeper.
Hah, Symbol.to_sym. At first I thought that was just an inherited method, but
Symbol.instance_methods(false)indicates that it’s defined explicitly for the Symbol class… Anybody have any insight as to why?Side note to Peter C.: the code block does not appear to be working.
duwanis: I would guess that it is so that you can call to_sym on a Symbol without worrying about it complain that the method doesn’t exist…the whole duck-typing thing. :-)
I think it’s because of the CSS reset I’m using. I’ll need to redefine what CODE means ;-) Thanks!
