A.1.1 grammar-note: parens

"A look-ahead of one character is required to distinguish function patterns"
    Change "function patterns" to "a FunctionCall".

"from a QName or keyword followed by a Pragma, or Comment"
    Delete comma.

"for (: whom the bell :) $tolls = 3 return $tolls"
    This example is illegal. Change "=" to "in" ?

(this note)
    What's so special about this particular case that it deserves to be pointed
    out? There are lots of other cases that require lookahead (in a lookahead-
    based parser), and more lookahead than just one character. I think this
    grammar-note should be dropped.
