HELP
Each non-composite data type may
be in one of five data shapes:

* Scalar is a single value such as 10 or 
  (32, @10).
* Array 1D is a one-dimensional array of
  values.
* Array 2D is a two-dimensional array of
  values.
* Array 3D is a three-dimensional array of
  values.
* Array is an array with one to ten
  dimensions.

Note that an input data shape constraint is
"Any" when the object accepts containers of
more than one of the data shapes.
