[boost] [boost.range] late addition, votes needed

Dear All, In the pre-redmond mailing Walter Brown discusses the possibility of adding these members to standard container classes: const_iterator cbegin(); const_iterator cend(); const_reverse_iterator crbegin(); const_reverse_iterator crbegin(); The motiviation is that we want to be able to say explicitly "give me a const iterator" without doing ugly casts. IMO a sound idea. Given the framework in boost.range these would be absolutely *trivial* to add. 1st vote: for or against adding these? 2nd vote: which naming scheme to use: a: cbegin(), cr_begin() b: const_begin(); const_rbegin(); The motivation for chosing the latter could be that "cr" contracttions become harder to read. Let me know what ya think. best regards Thorsten
