| [section References] |
| |
| References are functions. They hold a reference to a value stored somewhere. |
| For example, given: |
| |
| int i = 3; |
| char const* s = "Hello World"; |
| |
| we create `references` to `i` and `s` this way: |
| |
| ref(i) |
| ref(s) |
| |
| Like `val`, the expressions above evaluates to a nullary function; the first one |
| returning an `int&`, and the second one returning a `char const*&`. |
