[Qt-interest] Regarding the macros in QT

[Ian Thomson]

Hi,

The common macros you will find in Qt are the Q_OBJECT and other 
introspection macros. These are useful because C++ lacks introspection.

There's also some additional functional macros such as foreach, which 
acts very similar to BOOST_FOREACH. I consider these macros to be 
reasonably friendly.

I wouldn't label any code bad only because it uses or does not use any 
particular part of a language. It's true that macros are very often 
evil, but they can occasionally solve problems in a much cleaner way 
than any other method. I think Qt's use of macros is pretty sensible and 
clean.

Cheers,
Ian.
