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.

[thezip]: Is there an analogy for '&' (ie. run commandline process in background) for Windows commandline?
[Corion]: thezip: start "some title" path\to\that\ application, but that will open another console window
[Corion]: thezip: If you want to confuse your users, use system(1, "that\\command" );, which will make Perl launch it in the background
[Corion]: That will keep the console window open even though the user can't type into it anymore
[thezip]: So I have a script that generates a log file. After script completion, I want tohave VIM open this logfile.
