Aliasing document.querySelector y document.querySelectorAll

Hola, estoy tratando de crear un alias para las dos funciones del título así.

 const $ = document.querySelector; const $$ = document.querySelectorAll; $$("a")

Pero al ejecutar $$("a") aparece el error Uncaught TypeError: Illegal invocation .

¿Porqué es eso?
