understand why ";" on its own without a statement in front of it is an error,

I mean, LOGICALLY the ; and the line break should be the same, right? But no.
You can have a line break in places you can't have a ; and... ok then?
That's how the grammar reads. A `compound list' can start with 0 or more
newlines, but not a separator op like `;' or `&'.
