In dynamically typed languages writing such a construction is very easy 
because one can simply allocate an array at runtime of the needed type (if 
there are multiple types at all).

In Pascal, being a statically typed language, the array element does 
matter and cannot be decided about at runtime. Allocating an array at 
runtime is possible to, but inefficient because the size isn't known in 
advance, growing it one element at a time is a good way to fragment the 
heap.
