List Iteration Expressions

This sections lists a few frequently-used list iteration expressions.

Name(parameters)	Description	Example
for [item] in [list] return [expression]	iterate over a list	for i in [1,2,3,4] return i*i = [1,4,9,16]
sum (for [item] in [list] return [expression])	iterate over a list and return the sum of iterations	sum(for i in [1,2,3,4] return i*i) = 30
every [item] in [list] satisfies [expression]	test if every item in the list satisfies the test condition described by the expression.	every n in [12,50,51] satisfies n > 5 = true every n in [12,50,51] satisfies n < 50 = false
some [item] in [list] satisfies [expression]	test if at least one of the items in the list satisfies the test condition described by the expression.	some n in [12,50,51] satisfies n > 50 = true some n in [12,50,51] satisfies n > 51 = false
