Does $scalar = @array produce a scalar containing the size of the array?

Yes. But $point is a strange name for the size of an array!

If that is meant to be short for $lastPoint, it is still deceptive as with zero-based arrays, the index of the last point in the array is one less than the size of the array.

(Which incidentally, can be obtained using my $lastPoint = $#array;)
