Gather/Take

The gather/take construct was borrowed from Perl 6 and it's an interesting one.

var arr = gather {
    take(1)
    take(2)
    take(3)
}
say arr             # prints: [1,2,3]

Inside a gather{} block, the take keyword is available, which accepts a list of arguments that are stored inside an automatically created array. In the end, the gather returns the array to the caller.
