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.

No, this isn't a Boost policy. Many Boost libraries are entirely  
template libraries, so all of their code goes into headers anyway.

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?
