This PR aims at solving the issue of not currently having a way to distinguish a static list of children from a dynamic one (e.g. a List.map).
Any solution that suppresses React warnings for lists without key is IMHO bad and it would be better to provide a way to express a static list of children; this should not be the default and using it will be a conscious choice, so we will never hide the warnings to the developers so they will realize when they missed to pass the keys.
More details and the logic behind it are in the discussion of the Issue #21
