Boost slot compatibility

I'm glad to see compatibility with Boost slots among the new features. I hope TrollTech has realized that to stay competitive, Qt needs to play well with other tools rather that live in a world of its own. I hope TrollTech will kill moc in favor of Boost slots one day.

Yeah, that's a good thing! But I'm much more excited about tiny-SVG support, proxy models and pbuffer support.

moc provides more than just signal/slots. It also adds extended rtti, introspection and properties.

And the meta object model is so _incredibly_ useful. When I came to C++ from Python and Java
in 2003 to pick up on Krita, I was amazed that my classes weren't objects -- I couldn't do
introspection, I couldn't do meta programming, nothing dynamic seemed to work. QObject was a
godsent for me.

And without the meta object model extremely cool developments like the smoke library that
makes developing language bindings for Qt and Qt-based libraries a snip would be impossible.

Partly it's a mindset thing. Sure C++ doesn't give you much in the way of doing meta-object work dynamically, but it gives you very powerful capabilities for doing this stuff statically. In a lot of cases, you can make a static approach work (and often work better), but it's hard to look at it with the proper mindset to see how it could be done.
