I've had some code written with boost 1.53 a while ago that uses fusion maps to define at compile-time packet structures. There is then compile time generated code that handles marshaling, unmarshaling, and packet size calculation on these structures. One of the big reasons for going this route was the ability to have arrays contained in the packets. When upgrading from boost 1.53 to 1.55 on my Gentoo box, this all broke.

I'm contacting the list to ask if the use of arrays in containers was just a fluke or if it should be working and something happened in 1.55 (or possibly 1.54 which I never tried.)

Not an official answer in any way, but considering it's not explicitly documented as supported and your test case also fails when replacing `fusion::map` with `std::tuple` I would consider it just a fluke in the past. On the other hand, the following code compiles correctly (albeit with possibly a warning): typedef std::tuple, // note std::array std::string > test_t; test_t test{1, 2, {}, {"hello"}}; The same is not true for a `fusion::map`, and I think supporting that case would be worth it.
