I've thought about this some more. There is a reasonable way to recognize this, namely to check if the expression after the throw keyword is of type ZEND_AST_OR or ZEND_AST_AND. The expression above will fail with this message (given that $condition is false): ``` Fatal error: Uncaught Error: Can only throw objects in ... ``` IMO this is clear enough that a message for this edge case is not necessary.
