Class array_ref< T >: The existing array_ref classes make the view const. It may be useful to extend that to allow modifications of the referenced array elements, and use array_ref<const T> for immutable views.
Class flecsi::run::context::index_subspace_info_t: Currently only for unstructured mesh types. However, this needs to be extended.)
Member flecsi::util::array_ref< T >::array_ref (const std::array< T, N > &a): Arguably, this conversion should be a std::array conversion operator.
Member flecsi::util::array_ref< T >::array_ref (const std::vector< T, Allocator > &v): Arguably, this conversion should be a std::vector conversion operator.
Member flecsi::util::array_ref< T >::operator std::basic_string< T, traits, Allocator > () const: Arguably, this conversion should be a std::basic_string constructor.
Member flecsi::util::array_ref< T >::operator std::vector< T > () const: Arguably, this conversion should be a std::vector constructor.
Member flecsi::util::array_ref< T >::pointer: Should the pointer type be configurable as a template argument?
Member flecsi::util::array_ref< T >::substr (const size_type pos, const size_type n=size_type(-1)) const: See basic_string_ref::substr for interface questions. We want something like this on array_ref, but probably not with this name.
