Just note that in Simula - which has Algol 60 as [small] subset -
the couple books I have also speak about "passing" parameters,
or speak about associating actual parameters to the formal ones;
depending on what abstraction level they formulate.

It's also inefficient (and it shows some IMO undesired effects).

Yes; Simula inherited that mechanism; it has 'value', 'name' (and
also, for objects of class T types, 'ref(T)').
