Appender is a small wrapper that enables you to get an output 
range from a built-in array. It allocates using the GC. If you 
have an array and you need to pass it to a function that takes an 
output range, you can use it.

std.container.Array is a reference counted container that is 
equivalent to std::shared_ptr<std::vector<T>> in C++. It is not 
reliant on the GC.
