creates to functions x and '@' definition {x=y}.

quoting disables any interpretation in rc; this isn't
the bourne shell.  what the parser sees is the following
tokens.
FN WORD '{' WORD '=' WORD '}'

 in this case 'x' for some x should be interpreted
differently than for shell input.  the *name* of the token
is 'x', not its value.  (such tokens typically have no value.)

it does not matter that the first WORD is
defined as 'x @'.
