Creating a New View

Note

TODO: an actual tutorial, for now the main points are listed.

• Template on the aliased type. For type T expect T and const T

• Use traits to work out the correct const-ness of member types

• For template parameter T, View<T> should support implicit conversions from:

  • References to T objects

  • For T == const U, View<U> objects

• Comparisons should work between objects of type View<T> and all objects for which implicit conversions are allowed.

• Comparison operations need to be defined symmetrically, i.e., make sure the view can be on the left and the right side of the operator.
