This code fails to compile with g++34 + current boost.cvs.
Test.cc:8: error: no match for 'operator[]' in 'boost::numeric::ublas::vector<T, A>::begin() [with T = int, A = boost::numeric::ublas::unbounded_array<int, std::allocator<int> >]()[0]'
u.begin() should return an iterator, and the iterator should define operator[]. Why doesn't this work?
If these are (supposedly) random access iterators, it's because the ublas people aren't using iterator_facade or iterator_adaptor to define them. -- Dave Abrahams Boost Consulting http://www.boost-consulting.com
