I am not actually a Boost developer, but have the following suggestion regarding boost.fusion: I find the macro BOOST_FUSION_DEFINE_STRUCT potentially very useful, but it does not provide means to influence the initialization list of the default constructor. Alternatively, means to emulate c++11 default initialization (the struct Foo {int x=10;} syntax) could be emulated. Such feature would be very useful, as it would minimize repetition and make it easier to ensure that uninitialized variables are nowhere used.
I already generate my structs from BOOST_PP sequences in a similar way to BOOST_FUSION_DEFINE_STRUCT to avoid having to write json serialization boilerplate, but a variant of BOOST_FUSION_DEFINE_STRUCT i am suggesting would make this task even simpler.
I've been meaning to cleanup the macros as they are currently in an unwieldy state. If you have interest in this and want to contribute some, that would be great. Feel free to email me privately and tell me more about your ideas. Regards, -- Joel de Guzman http://www.boostpro.com http://boost-spirit.com
