Not at all, not in the general case!

```d
cat.meow().eat().sleep().play();
```
is equivalent to
```d
play(sleep(eat(meow(cat))));
```
In other words, the result of `eat` is fed into `sleep`, the 
result of `sleep` is fed into `play`, etc. Your statement is only 
true if all those functions return a reference to `cat`.
