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)
{code}
