Subject: Re: Things That Newcomers to Ruby Should Know

Ruby has no pre/post increment operator!

x++ or x-- will fail to parse.

++x and --x will do nothing, infact they behave as multiple unary prefix 
operators.

-x is the same as ---x is the same as -----x and so on.

Ruby is not C, C++ or Java
