[Development] A modest proposal: disable lower-case keywords (emit, foreach, forever, signals, slots) by default

You know what would solve this? The ability to define a *reflection* 
operator (with proper name scoping) that could apply to statements 
and/or access protection specifiers.

   class MyObject

   public Qt::slots:
     ...slots here...

     Qt::emit this->bar();

     using namespace Qt;
     emit this->bar();

     none->emit(...); // *not* the Qt::emit operator

If we played this right, maybe we could even reimplement MOC using 
reflection? (Stuff like Q_PROPERTY however might be hard, depending on 
if these operators are allowed to take a *space* delimited list of 
arguments rather than comma delimited.)
