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.
