Bug 10692 – Deprecation isn't checked using alias this

I would expect accessing members of B to fail when accessed with alias this: struct B { int i; } struct A { B b; deprecated alias b this; } void main() { A a; a.i = 5; // Deprecated assert(a.i == 5); // Deprecated }

Note that a plain 'alias' declaration specifically does not add modifiers, storage classes, attributes, etc. It's not a wrapper. It just forwards the lookup to the symbol. It should ignore any attributes, like plain alias does. Added a clarification to the spec: https://github.com/dlang/dlang.org/pull/2487
