By "feature" you mean having variables whose name ends in a caret (or
other escape character)? It's true that existing *nix shells don't,
but the OS does support them (and so hypothetical shells could do as
well):

(let ((process-environment (cons "ca^=with-caret" process-environment)))
  (shell-command-to-string "python -c 'import
os;print(os.environ[\"ca^\"])'")) ;=> "with-caret\n"
