* Mutator and Generator where merged. * A single pass over all duplications was made. * It is clear a specific handles?(node) code for finding mutators is needed. Like virtus does for attributes, should also cache. * Does not pass on 1.9 mode currently as blocks are unexpectly parsed differend when it comes to a series of literal booleans.
