QtE 5 works great on Win32/64, Linux 32/64 and Mac OS x 64. The 
main difference is that Qt5 uses a set of pre-defined slots and 
signals rather than creating them using a MOC or creating them 
dynamically as dqml. Qt5 has several large applications running 
on dozens of computers in different companies. If you use dynamic 
slots and signals from qml in Qt 5, you can fully play all the 
functionality of Qt5 with dlang. But this is a very big project 
of the future ...
