I admit I am no expert in D, I've written just a couple of hobby projects in it... but this sort of thing is actually much easier in D because it has associative arrays.
About comptime, it seems to me it's trivial to do that in D.
I started a little implementation of StringMap based losely on the Zig example, but I just did enough to show how D's templates and associative arrays could be used to implement that:

You can see that the creation of the map does not generate any Assembly, so it's run at comptime:
// comptime values!
static immutable entries = ["foo": 1, "bar": 2, "zort": 3];
enum map = mapOf(entries);
Notice that in D, "enum" can be used as a compile-time only variable, see https://dlang.org/spec/enum.html#manifest_constants
The Assembly seems to be almost all related to the associativ

e array implementation generated by the D compiler.
EDIT : if you want to try to continue the impl, have a look at the D's template tutorial: https://github.com/PhilippeSigaud/D-templates-tutorial/blob/...
D templates can do pretty much anything.
