Description

The list expression contains a list of streams. It opens, reads and closes each stream sequentially. Sample syntax:

list(expr,expr, ...)

The cell expression gathers the tuples from a stream and flattens them into a list in a single celled tuple. Sample syntax:

cell(name, expr)

In the tuple emitted by the cell expression the name param is the key which points to the flattened list.
