class A{
    int f(int a){
        return a;
    static A defaultA;
    static this(){
        defaultA=new A();

void f(int delegate(int) arg=&A.defaultA.f){

void defaultCall(){

fails with Error: cannot inline default argument &defaultA.f

whereas it did work previously.

This might be indeed correct if the compiler cannot guarantee that the correct
value of defaultA is used (i.e. after the static initializer).

It seemed to work correctly in my use case, and the fact that setting defaultA
to another value is most probably not "seen" by default value shows that using
null as default value, and an 
    if (arg is null) arg=&A.defaultA.f;
in the body is probably a better solution.

I still submit it here, but most likely this change is a feature, not a bug.
