5) Try and keep the 'MACRO laden' implementation under control
6) Be less 'monolithic'
7) Integrate more cleanly with standard C++ I/O streams
(where possible -- extend them where needed)
The biggest issue I have with ACE is that it is just way too much
sometimes. If I want to write a simple client app to download a
web page from a URL and process it, I have to take the threading
library and everything else. Not only do I have to download it,
but I have to compile and link to it. Boost has the opportunity
to not fall into this trap from the start.
So I think we should be careful to keep it simple. I think it is
interesting that in Hugo's current implementation, no library is
required. Very nice. I won't be surprised if we need a real
library at some point, but it won't be anything like the size of

They also discuss other issues like performance. I'm in
total agreement with you that exceptions should be the 'out-of-the-box'
policy, but if we can support BOOST_NO_EXCEPTIONS that would be nice.
As described here:
