Would replacing ‘ :: ‘ with ‘ . ‘ create ambiguities in C++?

Due to attempts to make C++ mostly compatible with the existing C code (which allows name collisions between object names and struct tags), C++ allows name collisions between class names and object names.

Which means that:

struct data {
    static int member;
};

struct data2 {
    int member;
};

void f(data2& data) {
    data.member = data::member;
}

is legit code.
