Should I choose a hash, an object or an array to represent a data instance in Perl?

I was always wondering about this, but never really looked thoroughly into it. The situation is like this: I have a relatively large set of data instances. Each instance has the same set or properties, e.g: # a child instance name age height weight hair_color favorite_color list_of_hobbies Usually I would represent a child as a hash ...

Checking all array values at once

Array Performance very similar to LinkedList - What gives!?

So the title is somewhat misleading... I'll keep this simple: I'm comparing these two data structures: An array, whereby it starts at size 1, and for each subsequent addition, there is a realloc() call to expand the memory, and then append the new (malloced) element to the n-1 position. A linked list, whereby I keep track of the head, ...
