madcowswe | 15:9c5aaeda36dc | 42 | * class XprVector is known as an anonymizing expression wrapper because |
madcowswe | 15:9c5aaeda36dc | 43 | * it can hold any subexpression of arbitrary complexity, allowing |
madcowswe | 15:9c5aaeda36dc | 44 | * clients to work with any expression by holding on to it via the |
madcowswe | 15:9c5aaeda36dc | 45 | * wrapper, without having to know the name of the type object that |
madcowswe | 15:9c5aaeda36dc | 46 | * actually implements the expression. |
madcowswe | 15:9c5aaeda36dc | 47 | * \note leave the Ctors non-explicit to allow implicit type conversation. |
