I finally was able to reproduce this problem with a small example: // Code begin class Base { private char[] myfoo; private char[] mybar; // Get/set properties that will be overridden. void foo(char[] s) { myfoo = s; } char[] foo() { return myfoo; } // Get/set properties that will not be overridden. void bar(char[] s) { mybar = s; } char[] bar() { return mybar; } } class Derived: Base { alias Base.foo foo; // Bring in Base's foo getter. override void foo(char[] s) { super.foo = s; } // Override foo setter. } void main() { Derived d; with(d = new Derived) { foo = "hi"; // Error! Due to the alias up there. d.foo = "hi"; // Works bar = "hi"; } } // Code end DMD 0.161 through 0.166 output: test.d(26): need 'this' to access member text I was able to find a workaround, simply put the alias after the function in the class instead of before.
