attempt made for 0124 to catch some of these.

Example?
Additional Comment #3 From fry 2010-03-17 13:14
i'd say try an example or two, remove brackets, and see how it responds.
there's a slightly massaged version, but what's thrown up from antlr is
kinda rough for the young'uns.

realized you may not have received the updates on this one.

Will reopen if given complete example program text.

void setup()
size(200, 200);
line(20, 20, 80, 80);
}
produces "unexpected token: size"

void setup() {
size(200, 200);
line(20, 20, 80, 80);
}
}
produces: "expecting EOF, found '}'"
Additional Comment #7 From MrFeinberg 2010-04-12 14:08
What would a better message look like for those errors? I have to admit, they both look good to
me. How would we know what kind of unexpected token it is?

I guess the expecting EOF one could be caught, but I'm really dubious about the other one!
Additional Comment #8 From fry 2010-04-12 14:11
nobody in our audience knows what a token is, nor what EOF is. don't worry
about it though, i think it's something to watch for the time being. given
bug #1539, i'm hesitant to try to be too clever about it unless we can be
100% certain about what's going on.
