Joel Bernstein commented on SOLR-10753:
---------------------------------------

The array is really just designed to support vector math operations. The next 
step is a matrix which wraps arrays to support matrix math operations. I think 
it makes sense to keep these two structures focused on vector and matrix math.

The list is more just a general purpose container for Streaming Expressions.

If the function name array is too general, perhaps we can just go with vector 
or vec?
