bash -c 'printf %s\\n "$0" "$@"' arg0 arg1 arg2 arg3

"The string" refers to the part which, in this example, is
single-quoted, and the arguments are indeed after that, not within it.

That would suggest to me that arguments in the place of %s\\n in my
example are assigned to the positional parameters, which is not true.
