Hi Dennis,
Sorry, I am not in favour of this if this means that I would loose the
possibility to index arrays with text or to have to specify the
array size in
advance.
Marielle,
I also use the current array capabilities and do not want to lose
anything we have. In fact I am in favor of expanding them further.
What I propose is a different array organization that is optimized
for execution speed and space efficiency at the cost of a more
restricted organizational flexibility. The restrictions would only
occur if you wanted to make this tradeoff for a particular array.
There are many problems that would benefit from this, but not all.
Mathematical problems would benefit from the packed arrays I propose,
while many indexing and database like problems benefit from the
sparse arrays we now have.
