1.2.1223. Trait Not Found

A unknown trait is mentioned in the use expression.

The used traits all exist, but in the configuration block, some unmentioned trait is called.

Be aware that the traits used in any configuration block may originate in any use expression. PHP will check the configuration block at instantiation only, and after compiling : at that moment, it will know all the used traits across the class.

<?php
class x  {
    // c is not a used trait
    use a, b { c::d insteadof e;}

    // e is a used trait, even if is not in the use above.
    use e;
}
?>
