Re: [boost] [mpl][patch] mpl::begin<an_integral_c> fails to compile

Tobias Schwinger <tschwinger@neoscientists.org> writes:

WHAT: =====

An instantiation of "begin<T>::type" fails to compile if T is an MPL Integral Constant. 'begin' is supposed to return 'void_' for all types that do not model the MPL Sequence concept. The bug also causes is_sequence' to fail.

FILES: ======

- begin_end_impl.hpp.patch

changes needed to make things work like documented

- is_sequence.cpp.patch

inclusion of the problematic case in the test suite

diffed against: CVS HEAD

Looks good to me. Please apply to HEAD and, (unless Aleksey contradicts me) after you see the test results, also to the RC branch. -- Dave Abrahams Boost Consulting www.boost-consulting.com
