Re: Why ref($proto) should be avoided

[frag]

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.
