pragma(msg, os.stringof...?);
pragma(msg, target.stringof...?);

what is use case for this? mixin & import

Long list of version.....
version(Windows)
    mixin(import("foo_windows.enum."));
else version(AArch64)
    mixin(import("foo_aarch64.enum"));
else
    static assert(0);

Shorter with one line
mixin(import("foo_" ~ os.stringof ~ ".enum."));
mixin(import("foo_" ~ target.stringof ~ ".enum."));

There's no built-in way, but you can define it yourself in a helper module:

version(Windows)
    enum os = "windows";
else version(AArch64)
    enum os = "aarch64";
else
    static assert(0, "unsupported os");

First, I will note that "windows" and "aarch64" are not in the same category...

Second, there are some already-built parts in phobos:

I also went ahead and did some for arch and runtime flavor, in a project where I needed these, feel free to steal (Boost licensed):
