But this seems to be in contradiction with the docs, which say [1] (emphasis mine):
The **global** |operator<<| has been overloaded for generic output streams such that Sequence http://www.boost.org/doc/libs/1_47_0/libs/fusion/doc/html/fusion/sequence.ht...(s) are output by recursively calling |operator<<| for each element.
Perhaps the authors were relying on ADL to find operator<<, but overlooking the fact that not all sequences would be in the boost::fusion namespace?
Thanks. That's certainly not correct. Adapted sequences in other namespaces can't avail of that. I just fixed the docs to avoid further confusion.
Why not just overload operators << and >> in the global namespace, as the docs say, rather than overloading them in the boost::fusion namespace? Regards, Nate.
