I'm an xbase (dbase/FoxBase & Pro/Clipper) and cobol programmer from way
back. (Been writing code since 1980) Believe it or not, I make a VERY
nice living maintaining legacy code. Anyway, decided to learn a new
modern language. Hence Ruby. I wanted something that was completly OOP.
Anyway, been playing with it for a while. And having trouble getting
what Symbols are used for?

I know what they are (I've read the manuals). But what are the practical
uses for them? I mean, couldn't I just use a constant or a global
variable? I know symbols keep their name unique (even if used to id a
class or variable). But is that the only benefit?

Thanks...
