Loops

There are various different constructs for loops:

# Iterate over a sequence
for x in ["red", "green", "blue"]:
	stdout.formatln("Next is {}", x)

# Iterate over a sequence backwards
for x in ["red", "green", "blue"] reversed:
	stdout.formatln("Next backwards is {}", x)

# Get the index as well as the value
for i, x in ["red", "green", "blue"]:
	stdout.formatln("Item #{} = {}", i, x)

# Get all key/value pairs from an associative array
for key, value in dictionary:
	stdout.formatln("{} -> {}", key, value)

# A C-style for loop
for (int i = 1; i < 10; i++):
	stdout.formatln("i = {}", i)

# A C-style while loop
int j = 10
while j > 0:
	stdout.formatln("j = {}", j)
	j--

Con todas las manos que me acogotan, no puedo respirar
Con todos sus dedos me haría una torta, para festejar
Que no me estoy yendo solo de este lugar
