An other way to do this block overture/closure is to use the production

	stmt -> stmt ; stmt

or its nearest equivalent in your favorite notation.
This just gives ";" a high precedence.
Then blocks have to be explicitly cut off, e.g.

	if A then if B then S1; S2
      = if A then (if B then S1; S2)
     /= if A then (if B then S1); S2

Or you could require all syntax to be fully bracketed, as is LISP.
