But I do not like magic work, so if something work in same way in all
lists/arrays then this should work in same way in future, or it should
be explicit changed.

   array?[index] : null-safe

   array??[index] or array?[index?]: null-safe & index safe ?

   array.?getElementIfExists(index): null-safe & index safe
