It will still work. If you look at the type signature of @cImport in the language reference[1], it returns a type just as @import. So you can call @typeInfo on it. But instead of writing

  const win32 = @cImport({
    @cInclude("windows.h");
    @cInclude("winuser.h");
  });

You will write:

  const win32 = @import("win32");

Where the module "win32" is declared in build.zig.
