If the learning curve wasn't about vertical I'd love to take a look under the hood. One might cheerfully suppose that it's always obvious when an assignment is indicated but it's not hard to believe that life is not really so simple. Given the multiple usage of so many characters I'm astonished that the parser could ever have been got working at all. Agonizing accretion I expect. BTW that would also explain why that 'typedef' method you just showed me does what I want so painlessly -- the context of a typedef simplifies the parser's work.
