           Summary: Taking address of shared member function -> unshared

           Version: D2
          Platform: Other
        OS/Version: Windows
            Status: NEW
          Severity: normal

class Foo {

     shared void bar() {}
}

void main() {
     shared(void delegate()) d;
     auto foo = new Foo;
     d = &foo.bar;
} 

class Foo {

     shared void bar() {}
}

void main() {
     shared(void delegate()) d;
     auto foo = new Foo;
     d = &foo.bar;
} 

Error: cannot implicitly convert expression (&foo.bar) of type void
delegate() to shared(void delegate()) 


But this compiles:

class Foo {

     void bar() {}
}

void main() {
     shared(void delegate()) d;
     auto foo = new Foo;
     d = &foo.bar;
}

With dmd 2.053 this prints:

testx.d(9): Error: cannot implicitly convert expression (&foo.bar) of type void
delegate() shared to shared(void delegate())

Which shows the delegate is being typed correctly.

shared(void delegate()) is not the same type as shared(void delegate() shared)
