DIPs VS PythonNet

The reference compiler, DMD, is open source: https://github.com/dlang/dmd

But they don't accept just any Pull Request or features the community submits, understandably. There's a process called DIP for language improvements: https://github.com/dlang/DIPs/blob/master/DIPs/README.md

However, by some accounts, it's really hard to get anything through.

Given D already has so many feature, I find that to be a good thing , to be honest, by not everyone agrees, of course.

Borrow checking does not require lifetime annotations. D is a precedent there. Look at DIP25 and DIP1000.

There's no "nogc" containers in phobos, or allocators, or an idiomatic way to do safe manual memory management. It expects you to do it the C way. It's also impossible to implement some things because of how D does moving. There's a DIP in the works to change how moving works, but it's overly complicated and bound to introduce even more bugs. https://github.com/dlang/DIPs/blob/master/DIPs/DIP1040.md

D Is drafting up move semantics to interface better with C++. Although they're going a bit the Rust way in the current proposal. D has tried a couple of other strategies, but unique pointers and C++ interoperability kind of forced the hand of Walter Bright.

I looked into using .NET as a "backend" and the pythonnet library to bridge the gap, but unfortunately that library does not support async. To properly support it would require some kind of integration with the asyncio event loop APIs or implement the AbstractEventLoop interface and some how make it thread-safe - not even sure that's possible with the API design of asyncio itself.

If you're running the python within C# using Python.NET, then you're somewhat within-process and there are ways of sending the data across. (Return objects, channel/queues, whatever fits your use case.)

I was going to make a joke about Python .NET core .. but .. apparently it's a real thing.

I am not set on .NET, but just curious, so thanks for the suggestions. Interesting that it's billed as cross-plaform, but doesn't do it that well. I just searched 'python wrapper for .net' and found PythonNET. Also, it seems yes IronPython is active.

I created a Django based python project that interfaces to TIA Openness to create some Remote IO. To do this I use the pythonnet library. so that I can load the Openness DLL.
