```    31 Theories
```
```    32

```
```    39 Defining Logics
```
```    40
```
```    41 page 127: type constraints ("::") now have a very low priority of 4.
```
```    42 As in ML, they must usually be enclosed in paretheses.

```
```    65 page 223, top: lfp_def, gfp_def have missing braces around the argument of
```
```    66 Inter, Union
```
```    67
```
