 * evaluated without further context. If a subexpression is not of this type, a user-provided
 * fallback evaluator is invoked. To support all constant expressions that are also supported by
 * PHP (and not already handled by this class), the fallback evaluator must be able to handle the
 * following node types:
 *
 *  * All Scalar\MagicConst\* nodes.
 *  * Expr\ConstFetch nodes. Only null/false/true are already handled by this class.
 *  * Expr\ClassConstFetch nodes.
 *
 * The fallback evaluator should throw ConstExprEvaluationException for nodes it cannot evaluate.
 *
 * The evaluation is dependent on runtime configuration in two respects: Firstly, floating
 * point to string conversions are affected by the precision ini setting. Secondly, they are also
 * affected by the LC_NUMERIC locale.
