> The *list* expression contains a list of streams. It opens, reads and closes each stream sequentially. Sample syntax:
> {code}
> list(expr,expr, ...)
> {code}
> The *cell* expression gathers the tuples from a stream and flattens them into a list in a *single* celled tuple. Sample syntax:
> {code}
> cell(name, expr)
> {code}
> In the tuple emitted by the cell expression the *name* param is the key which points to the flattened list.
