Annotate `getFoo` with `return scope`:
```d
struct Foo {
string foo;
string getFoo() return scope const @safe { return foo; }
}
Wow. Thanks.
I tried this, but rearranged the return and scope like this
```d
// doesn't work
string getFoo() scope return const @safe { return foo; }
```
```d
// works
string getFoo() return scope const @safe { return foo; }
```

Can anyone help me get rid of this depreciation?
```d
struct Foo {

string getFoo() const @safe { return foo; }
}
size_t bar(in Foo foo) @safe {
return foo.getFoo().length;
}
void main() {
Foo("hello").bar().writeln();
}
```
```sh
$ ldc2 -preview=in --run foo.d

parameter `this` calling `getFoo`
