builtins contains itself recursively

[fricklerhandwerk]

Describe the bug

builtins contains itself, recursively.

This seems unintentional?

Steps To Reproduce

nix-repl> builtins.builtins.builtins == builtins
true

Expected behavior

nix-repl> builtins.builtins
error: attribute 'builtins' missing

       at «string»:1:1:

            1| builtins.builtins
             | ^

nix-env --version output

nix (Nix) 2.11.0

It has existed for a long time, so it's not worth breaking someone's expression over what seems to be aesthetics, it is unlikely to cause problems and

It kinda makes sense
