if ((isInputRange!Range || isIterable!Range) && !isInfinite!Range && !isStaticArray!Range || isPointer!Range && isIterable!(PointerTarget!Range));
Allocates an array and initializes it with copies of the elements of range r.
Narrow strings are handled as a special case in an overload.
Range r range (or aggregate with opApply function) whose elements are copied into the allocated array
allocated and initialized array
auto a = array([1, 2, 3, 4, 5][]);
assert(a == [ 1, 2, 3, 4, 5 ]);
