There's no way that that's ever going to become an error. It's just too 
useful. The issue has come up before, and it's not going away. The prime 
example is constructors.

this(int a, string b)
{
 this.a = a;
 this.b = b;
 ...
}

Too many people would get annoyed if they were required to name their local 
variables differently - especially in a case like this. If you want to avoid 
the problem, then just don't name your local variables the same as your member 
variables - the most obvious solution being to do name your member variables 
differently - e.g. by prepending them with _.
