I suppose we have a rule delimiter ; as well. And lines are assumed to continue over any whitespace unless a rule delimiter is encountered.
example rule:

genericAssocList
    :   genericAssociation
    |   genericAssocList ',' genericAssociation
    ;

Although I haven't seen the statement delimiter mentioned in most of the languages, probably a useful thing to include ? (most new languages use a semicolon, but some older ones use newlines / full stops as well)
