For the description for @nogc functions as found here:
https://dlang.org/spec/function.html#nogc-functions

It is not indicated that "new" declarations may be compatible with "@nogc"
functions provided that they are only used for "scope" variables.  The
following program compiles on the dlang.org website:

```
class Bob {
        int a;
}

void doThing() @nogc {
        scope auto b = new Bob();
}

void main() {
        doThing();
}
```
