I see little use for this complicating feature and
would not allow it. All named integers would
start at 0, and increase sequentially by 1.

Same comment applies. Do not supply that
feature. There are many instances where
named integers would be a big improvement,
and only relatively few that would benefit
from relaxing the restriction that they all
start at 0 and increment by 1.
Keep it simple.
