You can use interfaces as class wrappers if you want referenced-counted class instances in Delphi. All arrays and strings are automatically reference-counted, and records (structs) are values that can be passed around without allocating memory (Delphi supports variable parameters, or pass-by-reference, but without requiring pointers or address-of notation).

As a Delphi application developer, you will most likely not be manually allocating/freeing memory a lot. Delphi's visual component library has a component ownership model. For example, any components/controls that you drop on a form are automatically "owned" by the form and are created/destroyed for you.
