Re: [Boost-users] [BGL] Updating to CVS version, typedef ... Graph not working?!

I think there's probably a better way: put all the concepts in a nested namespace of boost and then add a using-directive to expose them in boost... Although I'd really like to see the whole test program first, because it's not obvious where/how the collision occurs.

This looks like fallout from recent changes to the concept checking
library. There is now a template called "Graph" in namespace boost, and we
find that as well as your "Graph" typedef.

This might force us to go back to the "Concept" suffix on concept checking
templates, if this problem affects many compilers :(
