Yeah, my point about signaling intent.

Well, there's a diff between majority I mostly don't use and *all that are never used*, but YMMV. I don't lose *much* sleep over this. :> >> Nope, :foo and :Foo are different symbols, no doubt about that. > > You miss the point.

Right, nor should they since those are different symbols. > But if you are using a value > bound to the name foo, referring to it as Foo gives an > immediate NameError. Ah, of course. I don't really see that as a benefit here, since the joy of symbols is how lightweight they are. Just write one in place and go. Enumerations and using variables bound to strings as symbols both lose some of that joy since you have to do more work, which equates to me to having less fun. But, obviously, this is one of those things that strikes different people differently.
