struct SomeStruct
{
     void foo() {
         // use SomeStruct
     }
}


void broken()
{
     void function() foo = &SomeStruct.foo;
     foo(); // runtime error, isn't actually safe uses wrong 
calling convention as well
}

Not really lack of feature so much as there exists broken code. 
This has been valid code for god knows how long. At some point it 
was usable in @safe, but it looks you can't take an address of a 
member function without "this" as well in safe anymore.
