> The *cat* expression concatenates streams. Sample syntax:
> {code}
> cat(expr,expr, ...)
> {code}
> This *list* expression gathers the tuples from a stream and flattens them into a list
in a single tuple. Sample syntax:
> {code}
> list(name, expr)
> {code}
> The *name* param is the key in the tuple pointing to the list.
