Ranges are first class citizens, enabling them to be used and manipulated as values themselves, in for loop syntax, in array/sequence element selection, and in sequence generation.
myrange := 1..10 ## default step is 1
for i in myrange,
j in 9..-2..0: ## here step is -2
print( %s i %% ", " %s j )
## Note: The support of the following is not yet complete.
even := c"0123456789"[ 0..2..10 ] ## selects every second character
for c in even:
print( %s c )
myarray := [ myrange... ] ## expands the range in-place
