Issue ID: 20040
Summary: dip1000 implicit delegate attribute stripping fails
Product: D
Version: D2
Hardware: x86_64
OS: Linux
Status: NEW
Severity: enhancement
Priority: P1
Component: dmd
Assignee: [email protected]
Reporter: [email protected]
struct A {
void method() pure @safe nothrow @nogc { }
}
void test(scope void delegate() del) @safe { }
void main() @safe {
A a;
// OK:
void delegate() del = &a.method;
/*
onlineapp.d(19): Error: function onlineapp.test(scope void delegate() del) is
not callable using argument types (void delegate() pure nothrow @nogc
@safe)
onlineapp.d(19): cannot pass argument &a.method of type void delegate()
pure nothrow @nogc @safe to parameter scope void delegate() del
*/
test(&a.method);
}
The above code works fine - as, I believe, it should - unless I compile with
-preview=dip1000 . This issue breaks some of my toString() implementations, so
a fix would be appreciated...
