'start-file-process' on Emacs 28, used by Eshell on Emacs 28.

When giving more than two arguments to 'setq', it becomes hard
to figure out what is assigned to what. As the number of
argument increases, the readablity of code decreases. This is
also true for 'setq-local'. For 'setf', the problem is even
greater, unlike 'setq', all arguments to 'setf' look the same.
