It doesn't work quite like that, but it does enforce using
"thisref.member" instead of just "member".

class SomeClass {

    void (*SomeOtherFunc)(void);

    void SomeFunc(this SomeClass& self)
    {
        //SomeOtherFunc(); /* compiler error */
        self.SomeOtherFunc(); // OK
    }
};

Gee, perhaps you have just skimmed the responses given to you. Maybe
reading this will help:
wg21.link/p0847
Maybe reading this would help further:
https://en.cppreference.com/w/cpp/language/member_functions#Explicit_object_parameter
And especially the example

struct C
{
    void bar();

    void foo(this C c)
    {
        auto x = this; // error: no this
        bar(); // error: no implicit this->
        c.bar(); // ok
    }
};
