Discussion:

The original intent ofvector::data was to matcharray::datain providing a simple API with direct access to the contiguous buffer ofelements that could be passed to a "classic" C API. At some point, the returntype became the 'pointer' typedef, which is not derived from theallocator via allocator traits - it is no longer specified to preciselyT *. The return type of this function should be corrected to no longeruse the typedef.

[2010-02-10 Moved to Tentatively Ready after 5 positive votes on c++std-lib.]

Proposed resolution:

23.3.13[vector]

Update the class definition in p2:

// 23.3.6.3 data accesspointerT * data();const_pointerconst T * data() const;

23.3.13.4[vector.data]

Adjust signatures:

pointerT * data();const_pointerconst T * data() const;
