Colin Williams was proposing calling arrays coming from array(5) as
'dimensionless'. So, for the moment, we have three ways to name such a

- 'rank-0'
- '0-dimensional' or '0-dim' for short
- 'dimensionless'

Perhaps the time has come to choose a number for them (if we have to
live with such array for a long time, as it seems to be the case).

However, as more I think on this the more I'm convinced that,
similarly to their higher dimension counterparts, we will not arrive
to any definite agreement and people will continue to call them in any
way he would be more comfortable with. IMO, this should be not a
problem at all because all three words express a 'lack of
