Sba7 nnour Nasser :-P

Just my own opinion (others may have another).

With C++, =E2=80=9Cget_five()=E2=80=9D desigate a function call, while =E2=
=80=9Cget_five=E2=80=9D  =

designate an object (well, if it's a macro, it designate who=E2=80=91kno=
w=E2=80=91what).

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:
