         1. Assert: _steps_ is either a set of algorithm steps or other definition of a function's behaviour provided in this specification.
         1. If _realm_ is not present, set _realm_ to the current Realm Record.
         1. Assert: _realm_ is a Realm Record.
         1. If _prototype_ is not present, set _prototype_ to _realm_.[[Intrinsics]].[[%Function.prototype%]].
-        1. Let _func_ be a new built-in function object that when called performs the action described by _steps_. The new function object has internal slots whose names are the elements of _internalSlotsList_, and an [[InitialName]] internal slot.
