Discussion:

I found a missing specification of the copy constructor of the following class templates:

- `slice_array` (28.6.5 [template.slice.array])

- `gslice_array` (28.6.7 [template.gslice.array])

- `mask_array` (28.6.8 [template.mask.array])

- `indirect_array` (28.6.9 [template.indirect.array])

Proposed resolution:

1. Before 28.6.5.2 [slice.arr.assign] insert a new sub-clause as indicated:

   -?- `slice_array` constructors [slice.arr.cons]

   >     slice_array(const slice_array&);

   > -?- Effects: The constructed slice refers to the same `valarray<T>` object to which the argument slice refers.

2. Before 28.6.7.2 [gslice.array.assign] insert a new sub-clause as indicated:

   -?- `gslice_array` constructors [gslice.array.cons]

   >     gslice_array(const gslice_array&);

   > -?- Effects: The constructed slice refers to the same `valarray<T>` object to which the argument slice refers.

3. Before 28.6.8.2 [mask.array.assign] insert a new sub-clause as indicated:

   -?- `mask_array` constructors [mask.array.cons]

   >     mask_array(const mask_array&);

   > -?- Effects: The constructed slice refers to the same `valarray<T>` object to which the argument slice refers.

4. Before 28.6.9.2 [indirect.array.assign] insert a new sub-clause as indicated:

   -?- `indirect_array` constructors [indirect.array.cons]

   >     indirect_array(const indirect_array&);

   > -?- Effects: The constructed slice refers to the same `valarray<T>` object to which the argument slice refers.
