Am not sure how you define the executor. Maybe that answers the question: http://svn.php.net/viewvc?view=revision&revision=298348
All traits related operations are done when the class is compiled. Similar to how interfaces are handled. For the composition there is an additional opcode which concludes the compilation of a class and executes all merge/conflict resolution operations. After that is done, traits do not have any additional impact on the execution anymore. > And I am assuming the class composition changes aren't going to blow up > opcode caches?

Don't know exactly. There is a certain need to adapt the opcode caches, I would guess.
