> As a former Smalltalk developer, what do you think about it would actually slow you down (despite popular claims re productivity in Smalltalk)? I was a Smalltalk developer in the early nineties as well, but then switched to statically typed languages and the source file concept for many reasons (performance, testing effort, integratability, etc.). For the present case performance is critical (parsing and cross-referencing of large code base) and also the specific required presentation/interaction features which come with Qt out of the box; and I already have a large toolbox based on C++ which I was able to reuse. > And is it one goal of yours, then, to mold Oberon+ so that it would eventually be at parity, productivity-wise, with C++? It would take more than a lifetime to achieve that goal given that my https://github.com/rochus-keller/

LeanQt and https://github.com/rochus-keller/LeanCreator/, which support my efficient toolbox today, have more than a million SLOC. My goal in the first place is to find out how I have to extend Oberon+ so I can use it in real-world (i.e. non-academic) projects with not too big restrictions compared to my current use of C++; reaching parity in terms of efficiency and the therefore required ecosystem is yet another challenge.

> Qt for MCU [..] seems like a big advantage over Qt LGPL-3.0. I have my doubts. MCUs powerful enough to run Qt GUIs smoothly are more expensive than, say, an i.MX6ULL with a Cortex-A7 application processor and Linux. It’s a lot easier to find developers for an embedded Linux system ... This is a very convincing argument. A Linux embedded system is also more flexible and the degree of code reusability is usually higher; it's also easier to develop and debug, and one can profit of a huge ecosystem (e.g. OTA update and the like). > Shall we use Qt LGPL-3.0 or Qt Commercial? LeanQt (https://github.com/rochus-keller/leanqt/) is still available under LGPL v2.1. I will not switch to Qt 6 with my projects.
