This compiles fine with with VC 7.1. g++ fails with:

This means that g++ doesn't do ADL for static_pointer_cast<int>.

Nor does any other compiler I know of, IIUC.

There's an

issue about it by Gabriel Dos Reis:

http://www.open-std.org/JTC1/SC22/WG21/docs/cwg_active.html#485

but it's still open and contains no further notes, so it isn't clear whether

g++ is right or not.

Well, if foo<bar>(...) starts doing ADL it's going to break a lot of code. I certainly leave off qualification when using that notation, knowing that ADL is avoided. -- Dave Abrahams Boost Consulting www.boost-consulting.com
