[boost] c.l.c++.m post

Hi, The enclosed post showed up on c.l.c++.m; AFAICT it has little or nothing to do with MPL, but it does contain several boost-related issues. The best answer isn't really clear to me; we could detect dereferenceability, use a hack involving get_pointer, or maybe something else would be appropriate. Would anyone like to tackle this one? -- Dave Abrahams Boost Consulting http://www.boost-consulting.com
