-A pattern that's just a variable binding,
+Patterns that bind variables default to binding to a copy of the matched value. This can be made
+explicit using the ```copy``` keyword, changed to bind to a borrowed pointer by using the ```ref```
+keyword, or to a mutable borrowed pointer using ```ref mut```, or the value can be moved into
+the new binding using ```move```.

 or bind a new variable.
