<p>This class represents an expression of a generic nullary operator. It is the return type of the Ones(), Zero(), Constant(), Identity() and Random() methods, and most of the time this is the only way it is used.</p>
<p>However, if you want to write a function returning such an expression, you will need to use this class.</p>
