"Deducing this (P0847) is a C++23 feature which gives a new way of
specifying non-static member functions. Usually when we call an object’s
member function, the object is implicitly passed to the member function,
despite not being present in the parameter list. P0847 allows us to make
this parameter explicit, giving it a name and const/reference
qualifiers. For example:"

struct implicit_style {
void do_something(); //object is implicit
};

struct explicit_style {
void do_something(this explicit_style& self); //object is explicit
};

We use the implicit this a lot.

Still waiting for the delivery of my gold star !

Great, C++23 doubles its own complexity (and, VISIBLE is important!) again.
So the boss knows they are brilliant and work hard, if I understand the feature correctly.
