Will boost signals and slots be moved to header files in the future?
I have no plans to do this. There is quite a bit of non-template code, and it would be a shame to inline it all. Binaries would get significantly bigger, I think.
Isn't it a policy to keep libraries in header files, if possible, or is it up to the library authors?
No, this isn't a Boost policy. Many Boost libraries are entirely template libraries, so all of their code goes into headers anyway.
In http://lists.boost.org/Archives/boost/2003/08/50815.php, the possibility of adding a macro to boost/config.hpp, which basically would result in including .cpp-files from headers, is mentioned. Are there any plans of adding such a macro or is it a bad idea?
I think it's a bad idea, because of the binary size issue above. Is there any particular reason why you'd like Signals to live entirely in headers? - Doug
