# How do I nest functions?

The following code

```
EllipticCurve([0,1]).reduction(5).cardinality()
```

returns an error, while the code

```
e = EllipticCurve([0,1]).reduction(5)
e.cardinality()
```

works fine. Is there a way to do this on one line? (Note: I don't particularly care about this with elliptic curves, I'd just like to be able to do things like this in one line. In other words, I'm not looking for a mathematical answer. Also, I'm asking for something different than, say, this

```
e = EllipticCurve([0,1]).reduction(5); e.cardinality()
```

.)
