Description

Currently the access to an item in a typed array requires a data copy, as the (shared) type and the data need to be copied to adjacent memory locations to allow for processing by the current pointables. Instead, the TaggedValuePointable could be changed to separate the tag from the value, so that they don't need to be in adjacent memory locations.
