Sba7 nnour Nasser :-P

Just my own opinion (others may have another).

With C++, “get_five()” desigate a function call, while “get_five”  
designate an object (well, if it's a macro, it designate who‑know‑what).

With Ada Get_Five may designate both a function call or an entity.

If I understood your matter, conclusion is: Ada has this from its very  
beginning.

Or are you seeking for expression functions introduced since Ada 2012 ?
If so, have a look here then:
