Hi Jumaroch, this is interesting, maybe you have solved things that I have not yet.
PySide2 builds completely, and a few things work on Qt5.4.
Qt5.5 right now has a problem with QSysInfo.
I am interested in your support for signals, because I did not do
that, yet. But before, there is the bigger problem of
the implementation of dynamicmetaobject.
That needs a re-write, and I did not understand exactly how.
The revision that PySide uses is still #3, which is no longer supported
by Qt5, they now require #7.
Was that the case when you worked on QtCore?
I would be very much interested in your patches, if it solves more than
in your list below, which I all have already.
Here is my status log of the project.

Thanks very much -- Chris
