regarging __autoload, everything is correct, actually, as throwing
exception doesn't let engine to try other variants (which is
counter-intuitive). it is perfectly fine to have several autoloaders
enabled.

regarding __toString(), I am not convinced that it is unresolvable.
Someone with better understanding of engine should comment
