-/// TODO: UPDATE DOCUMENTATION
-/// LLVM-typed implementation for generating a [`Producer`] that sets a list of ints.
-///
-/// * `elem_ty` - The element type of the `NDArray`.
-/// * `shape` - The `shape` parameter used to construct the `NDArray`.
-///
-/// ### Notes on `shape`
-///
-/// Just like numpy, the `shape` argument can be:
-///   1. A list of `int32`;   e.g., `np.empty([600, 800, 3])`
-///   2. A tuple of `int32`;  e.g., `np.empty((600, 800, 3))`
-///   3. A scalar `int32`;     e.g., `np.empty(3)`, this is functionally equivalent to `np.empty([3])`
-///
-/// See also [`typecheck::type_inferencer::fold_numpy_function_call_shape_argument`] to
-/// learn how `shape` gets from being a Python user expression to here.
