(I'm taking the liberty of responding because I understand Andrea
doesn't have time).
No user-visible feature is being added.
It's an internal data type for use by the compiler, essentially a hash
table indexed by integers (which may be negative) that keeps track of
the maximum and minimum assigned index values.
This simulates a vector that grows automatically, like JavaScript
arrays do, but it's not very fast (it doesn't have to be for this
application) and, if I understand correctly, not intended for general
use.
