Streams, also called lazy lists, are like lists except that
items are not computed until they're needed. This allows
for more efficient handling of large computed lists, and
even infinite lists. The only piece of magic is here in
IN FRONT OF STREAM, whose second input is of type
Unevaluated, which means that it's a procedure, with
a sort of invisible gray ring. So HEAD OF STREAM is just

The inputs are a stream and a positive integer. SHOW STREAM reports a
regular finite list of length less than (for short finite streams) or equal to the
second input. It's useful because an infinite stream can't be displayed in a
finite amount of time.pt:uma lista com os itens do canal _ até ao _ º
1001Make a stream from a finite collection of items, like the LIST primitive.
Since this block is typically used for small amounts of data, it does not
delay computation of its inputs.pt:um canal com _
1Call this block with STREAM WITH NUMBERS FROM 2
as its input to get the infinite stream of all the prime numbers.
It's called SIEVE because the algorithm it uses is the Sieve of
Eratosthenes (clickable link):
https://en.wikipedia.org/wiki/Sieve_of_Eratosthenes
Look inside; it's a beautifully elegant algorithm.
