I suppose it is neither a taco or a sand which, however it lives within the sandwich family. What’s weird is if we take the inner radius as it runs towards zero it would look no different to a sandwich (save the weirdly thick bread that looks similar to a burger), but it would be topologically different shape.
I suppose it depends on if you consider a bagle split more naturally a sandwich or not, and, if so, then it matters if the if the space of the filling being connected matters or not.
The M1 Mac book is my daily over Linux now. It’s a wonderful machine, it’s only concession is gaming can be a pain/not worth it. I like the “hobby” of it, but I know it’s not for every one.
