    @class      MPParenthesisFunction
    @abstract   A parenthesis function encapsulates a single expression and thus
                prioritizes it in evaluation.
 
    @discussion Prioritizing the expression means that the complete expression
                must be evaluated <i>as is</i>. No part of it can be <i>used</i>
                elsewhere before the parenthesis function has been evaluated.
