On the blackboard in the mathematics department it’s not.

But I get your point.

I have also heard the objection that [x] is a 1×1 matrix whose only element is ‘x’.

Square brackets can also denote the floor function (especially in old works where '⌊' and '⌋' were typographically unavailable).

An array is merely a function from N to some set.
