Forgive me for wading in on this, but

Public variables are a curse. They will come back and bite you when you least expect it.
There is no control. None. It's a bit like leaving your wallet on a bar thinking "Oh, no-one
will touch that."
Yes, having to declare a simple property that only exposes a state variable is so much of a 
pain. Oh, it takes an inordinate amount of keystrokes, probably about 20 or so. But, consider
the amount of effort that goes into finding the bit of code that someone else wrote that used 
a particular value of that variable "because it was handy".

Enough. Yes dont let them be overridden, better still ban the damn things in any class that has the
magic word "Export" in it.

Trust me on this. I know. Once upon a time I thought that an exposed boolean was safe. Ha! We 
had a young guy working for us that found a "magic" way to use specific negative values as flags 
with the obvious later disasters. 

The only thing that should ever be exposed unprotected is a constant. 
(I don't know whether it is possible to override a constant? And I'm not about to try. ....
AAAARRGH Override a constant with a public variable??? The mind boggles.)

Anyway. Sorry for butting in.

cheers
