Actually, since there are only two cases where the brackets may be empty,
I would suggest instead reading

	[N]	as "array N of"

and
	[]	as "array ? of"

and NEVER forget the sizes until The Rule allows you to do so.

The size of any array is an important part of the type of that array;
it must not be disregarded at whim.

(The Rule allows you to discard the size whenever an <object, array N of T>
is used in a value context.  The two cases where the brackets may be
empty occur when declaring formal parameters to functions, and when
declaring `extern' objects.  Even then, only the `innermost' set of
brackets may be empty, and only if they immediately follow the
identifier.)
