Hello,
Why doesn't this code compile?
```d
static struct Foo{
void *ptr;
void proxySwap1(scope ref typeof(this) rhs)scope pure nothrow
@trusted @nogc{
auto tmp = this.ptr;
this.ptr = rhs.ptr;
rhs.ptr = tmp;
}
void proxySwap2()(scope ref typeof(this) rhs)scope pure
nothrow @trusted @nogc{
this.proxySwap1(rhs);
}
void proxySwap3()(scope ref typeof(this) rhs)scope pure
nothrow @trusted @nogc{
auto tmp = this.ptr;
this.ptr = rhs.ptr;
rhs.ptr = tmp;
}
}
void main()@safe{
scope Foo a;
scope Foo b;
a.proxySwap1(b); //OK
a.proxySwap2(b); //OK
a.proxySwap3(b); //Error: scope variable `b` assigned to `a`
with longer lifetime
}
```
