in the thread about C# like properties we were talking about the advantage to be able to repere assignation to properties.
I assume by "repere assignation" you mean, in English, "represent assignment." ("Assignation" is not used, normally, as a synonym for "assignment.")
I said that, another way to repare the assignments is to use a free function assign_to, like we use the free function swap, or the cast family functions.
assign_to(a.p_X, 1);
assign_to call by default the assignment operator.
That's a reasonable default while permitting customization. The idea is reasonable, because it can be customized to recognize properties, however implemented, as well as normal data types, to provide a common "assignment syntax" that adapts to the types used. However, operator = can be likewise customized and is idiomatic for assignment. Why create a new name?
If we want transitive assignation
a = b = c;
we could do
assign_to(a, assign_to(b, c));
and if we find this not really readable we can try with
tie(a) = tie(b) = c;
Neither is good, but transitive assignment can be ignored; it is hardly a critical feature.
