Anything that has an expression starting with an operator, such as "-x".
polygon {Foo
    Foo
    -Foo2
    Bar
}

The point list will be interpreted as "Foo - Foo2, Bar".

This kind of error can be very difficult to track down. I *always* use 
commas, and always use logic which puts them where they are needed.
