This solves Tor bug #9701, complying with disk avoidance documented in
https://www.torproject.org/projects/torbrowser/design/#disk-avoidance.

 // even nested in an arrow-function parameter default value

 load(libdir + "asserts.js");

     "(...rest) => arguments",

     "(...rest) => (x=arguments) => 0",

     "function f(...rest) { return (x=arguments) => 0; }",

     "function f(...rest) { return (x=(y=arguments) => 1) => 0; }",

 ];
