Whatever Closure (II)

• Perl 6 tends to be smart about getting closure arguments
• @a[*-1] is the last element in @a
• If @a[ ] is passed a closure, it evaluates it passing the number of elements in @a as the argument
• So @a[*/2] is a middle element in @a
• And @a[1..*-2] is every element but the first and last
• 1, 1, * + * ... * is the infinite sequence of Fibonacci numbers

« first < prev (30 / 41) next > last »
