Detailed Description

template<class ElementType>
struct Aleph::default_accessor< ElementType >

Trivial accessor policy: access(p, i) is just p[i].

This is the only accessor policy this polyfill provides (matching std::default_accessor); custom accessors (atomic views, checked views, ...) are out of scope for this header.
