PS: I think a `deepCopy` won't be possible in general, no? If this is
correct, we could just name the method `copy` instead of `shallowCopy` and add
the according comments.
I'm also fine with both approaches. I just tried to imagine what _I_
(highly subjective :P) would look for as a user. But this is what the different
approaches would look like in practice, right?
```java
Tuple4<Integer, String, Double, Integer> toCopy = ...
Tuple4<Integer, String, Double, Integer> theCopy = new Tuple4<Integer,
String, Double, Integer>(toCopy)
```
vs.
```java
Tuple4<Integer, String, Double, Integer> toCopy = ...
Tuple4<Integer, String, Double, Integer> theCopy = toCopy.copy();
```
