  • You surely mean of course (defined $it and blessed $it and $it->isa('Foo'))...
    • That's a lot longer to type and while it's theoretically clearer, I don't think it wins over an eval. Did I miss something obvious?

      • In general, using eval willy nilly is not good because you might swallow an exception that should have bubbled up. But a properly working isa is not expected to throw exceptions (or so I hope), so this idiom seems just fine.
