I committed a fix for this a little while back. It should be working fine in
master now.

Maybe, but I think *cat* is maybe more intuitive then adding a parameter to
merge. In SQL we'll be implementing union and unionall with these streams.
But I think *list* is probably not the best name for the function.

Maybe merge should support and inOrder option which doesn't maintain sort

Merge is maintaining the sort order between the streams. List is concatenating
the streams.
I'd be happy changing *list* to *cat* and we could result the *list* function
for different behavior.

Also one thing about the current *list* is that it's a Streaming Expression.
While the array us a Stream Evaluator. So the list is actually iterating each
of it's list items and iterating them in order, basically concatenating
Streams. The array is simply return a list on numbers. So they have very
different behaviors.

One thing that we could do is have a split between containers that work with
Streams (list) and a containers that works with primitives (matrix, array).
This is would be a fairly clean split.

Dennis Gove commented on SOLR-10753:
The array itself isn't doing the vector math operations, though. Right? I'd
think it'd be up to the function doing the math operation to validate its
input, which means accepting a list that could be filled with anything is
alright - cause it'll be validated anyway.
I'm concerned that there'll end up being a lot of very similar things used for
very different reasons. And users will be confused about when to use which.

I'm going to commit what I have for this, it's a pretty small piece of code. We
can make it more generic with further work. Or we could always change the name
from array to something more specific. I'll leave the ticket open for further
work.

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?

Dennis Gove commented on SOLR-10753:
Could it just be a thing that returns an list of objects? Then it's up to the
container to handle whatever they are.
{code}
list(1,2,3,4)
list(1,add(2,3),if(gt(a,b),a,b))
list(1,"foo", search())
{code}
Basically, a single function that creates a list/array of whatever. It is up to
the containing function to decide if the list is valid for its purpose. For
example,
{code}
add(1, list(2,3,4,5)) is the same as add(1,2,3,4,5)
add(1, list("foo","bar")) is deemed invalid
{code}
And map with a list would allow things like
{code}
map(add(1,?), over=list(2,3,4,5)) would result in list(1 + 2, 1 + 3, 1 + 4, 1 +
5)

We've added a List which holds a list of Streaming Expressions. This returns a
list/array of numbers or strings.
I thought about using vector, but that seems to have a different meaning in
math.
I think in Lisp there is a make-array function.
It seemed array was just the simplest name for the function.
