Struct members are always public

[TheSpydog]

Describe the problem. What did you see? What did you expect to see?

All fields and functions of structs are public, even those without the public keyword. I would expect that those without the public keyword are private and inaccessible from outside the struct itself.

If this is a code issue, provide a minimal code example:

struct MyStruct {
        var privateInt = 3;
        function secretFunction() {
                printf("~secrets~\n");
        }
}

function main() {
        var myStruct: MyStruct = struct MyStruct;
        myStruct.secretFunction();
        printf("%d\n", myStruct.privateInt);
}
