Hi Dan,


thank you very much for your kind hints - quite interesting idea to have 
a more detailed look into this direction!

By the way, your response was the very first here, which I consider to 
have a constructive notion; at least I did not felt very welcome here by 
Chris until yet...

In the last project I developed the frontend on said C# - WinForms basis 
(C# and .NET is quite awesome! Most of it meanwhile has even become 
crossplatform! By the way, as Spyder also has this "just 3" notion, I 
already switched to VSCodium and never regretted that - VSCodium is the 
best free IDE for Python as well as C# yet, if you ask me:) and just 
parts of the backend with IronPython (which also is nice, although it 
just has access to a limited set of libraries). It worked fine, but I do 
not like mixing languages if not necessary as I deem that to be a 
software design weakness and it naturally comes with some overhead. 
Imagine, if another person one day should continue this work, he must be 
fluent in Python AND C#, not so easy to find someone free who is on the 
market I guess...

Blythooon solves the current issues well, so at the moment, there is no 
pressing reason for me to become frantic. But considering the long term, 
those thoughts are naturally real. The obvious trend to force people to 
switch to Python 3 might lead to people even eliminating the access to 
the old packages Blythooon is using. This sword of Damocles is a heavy 
burden.

If anybody thinks that is a little too much seeing on the black side, 
then they should attentively follow what at the very moment is happening 
with the current Qt version...

May I ask, do you have any knowledge or even experience about if resp. 
how good Tauthon and Pypy2 works together with Qt 4.8?

 From my experience the limitating factor during frontend development is 
nearly always the GUI part. Kivy seems to be nice, but scientific 
plotters alike PyQtGraph are Qt based and cannot easily be integrated in 
Kivy yet.


Have a nice day,
Best Regards
Dominik
