Description

Reference expression template that provides all operator overloads.

Note

Due to a limitation of Doxygen, each of the value(), left(), right(), and operator overloads listed here is a stand-in for three member functions. For each function f, the listing here is:

However, there are actually three functions:

`expression` public member functions

```
();
```
Default constructor. Does nothing.
```
( rhs);
```
Moves rhs into the only data mamber, elements.
```
 ();
```
A convenience member function that dispatches to the free function value().
```
 ();
```
A convenience member function that dispatches to the free function left().
```
 ();
```
A convenience member function that dispatches to the free function right().
