Yes I suppose `configurable` should be enabled. The reason I used delete instead of setting to null is that null is considered just as important a value as any other and if you had an outrageous number of nulls, it could consume a noticeable amount of memory. `free` only releases the data stored in the global pointer object, not the original variable itself, that's not possible. I don't know how many time's I've had to say this, but this was never intended to actually be used, just as a proof of concept.
