>document entity had user added key/value pairs
>stored as a public array
>every time a key/value was to be added, there was a copy-pasted snippet like that
>every time a key was to be looked up, there was a for loop doing linear search
>always duplicated, never as a method on the entity or even in the classes that used it most
>I eventually replaced it with a hash table and proper encapsulation.
