this function is assigned to a builtin function or function routine during the GC it may cause unresolvable
circle since one part of the circle is a weak reference (marked by GC) and the other part is hard reference
(reference count). In this case when the function which contains the tagged template literal collection
is getting GC marked the arrays in the collection are still holding weak references to properties/prototypes
which prevents these objects from getting freed. Releasing the property list and the prototype reference
manually eliminates the existence of the unresolvable circle described above. */
