[Development] Technical vision for Qt for Python

Dear all,

I am using PyQt since 10 years now and my points are:

- It is true that missing bindings is a serious issue to use PySide 
actually.
- I noticed PyQt has simpler wrapper code, but I don't investigated more.
- I would dream to have Python instead of JS, but we know how to 
implement a good JS virtual machine, for Python who really knows ???
- I experimented complex issues and I don't know how to debug them : we 
need a good debugging tool to figure out what happen in threads 
signal/slot ...
- A good tutorial : how to wrap your custom C++ classes (  maybe there 
is one ??? )
- I think that something like a white paper " how to make a reactive 
Python/Qt application " would help people to understand GIL issue and 
how to deal with it.
   Because we can make serious applications using Python/Qt and 
competitive with Electron.
- support async and pypy
- A referential of applications that just works ( I could provide 
https://github.com/FabriceSalvaire/book-browser )

Cheers
