D thinks it is OK to mess around with TypeInfo

[Yuxuan Shui via Digitalmars-d-learn]

For example

struct A{}
@safe void main(){
        import std.stdio;
        A a, b;
        auto y = typeid(a);
        y.name = "Nope, I'm not A";
        auto x = typeid(b);
        writeln(x);
}
Make changes to TypeInfo will affect all the future typeid() 
results! And D is OK with that?

IMO, TypeInfo returned by typeid() should be immutable.
