> it's small eco system makes me look over it. You have relatively clean access to all C libraries. But I do not know if that is relevant enough in your area of work/play. And the standard library is also pretty nice. Sure, it's nowhere near Python's Batteries-Included package, but it can get you quite far.

> You have relatively clean access to all C libraries. I thought much of the point of D as a programming language would be its "relatively clean" access to external C++ libraries, which is not a feature many other languages share? (whereas it is of course quite common to have a foreign-function interface with C.)

D is designed to make it easy - to the point that you can #include a C header file and you're good to go.

It looks like you still have to write interfaces for c libraries (https://dlang.org/spec/interfaceToC.html https://dlang.org/spec/interfaceToC.html) and that it can't use header files directly like zig. This is fine for interop but it's not great as a drop in replacement, there is still some manual work and likely many edge cases around macros in the c libraries. I'm yet to put zig through it's paces but you can include header files directly, theoretically that makes it a much better drop in replacement.

  You can write interfaces and for many projects that works fine. There are tools like https://github.com/jacob-carlborg/dstep https://github.com/jacob-carlborg/dstep to convert headers and tools like https://github.com/atilaneves/dpp https://github.com/atilaneves/dpp to "preprocess" the D source to include and translate headers

  You could write that as a library feature in D, technically (I'm guessing no one's done it, for obvious reasons)
