I was just reading some commentary/documentation and came across this:

(after all, we do not want to go down the road of global variables, which will inevitably lead to the Dark Side, do we?)

I'm as new to C as I am to cboard (is this issue consistent amongst all languages? I sense that it is...) but I really like global variables, such as flags, etc. -- buffers even!

So why do some people drops hints, vis. global variables are for losers?
