in reply to Why ref($proto) should be avoided
in thread My first stab at OO perl...

Still, that's after using ref($caller) in all the preceding examples. Ditto in the 'final version' of CD::Music (p.114). And you've got to admit, "probably better" aint much of a condemnation.

    Well, i wouldn't say all the preceding examples. He does use some form of ref($caller) extensively throughout the book, but not in every example.

    And i can admit that "probably better" ain't much of condemnation, but not as much as i can admit that it ain't much of a recomendation either. I see nothing wrong with simpler methods that are less prone to bugs and are more clearly self-documenting. :)

    Update: i should mention that Class::MethodMaker's new_hash_init specifier makes for a very robust instance constructor. Consider using it if you don't like having to write your own clone method.

[Corion]: Oh yay. Why do I test a migration with transaction code "T" when the real trades from the migration will come with P9N (which is excluded from the processing)?
[Corion]: (nothing that a quick SQL update can't fix in the input data, but why did the people organizing the test not plan that test under real conditions...)
