Any major difference between perl 5.00503 and perl 5.6?

scottstef has asked for the wisdom of the Perl Monks concerning the following question:

Greetings Folks,
Not sure if this is a SOPW question or a meditation, but after having it suggested by a saint for here, I will go with SOPW.I did a Super Search and didn't find anything really related to this old versus 5.6 mostly (5.6 versus 6)
I just installed debian's potatoe image on my system at home. It comes default with perl 5.00503. I have always used perl 5.6 so far in my brief perl career. What are the differences? I know local acts a little differently between the two. I just am looking for any screwy behaviors to be aware of before I write something that "I know is correct" only to have it flake out when I change perl versions
Any comments/suggestions here will probably save me hours of anguish. {grin}

I know a couple of differences: `open (FILE, "<", $file) # legal 5.6 only use warnings; # legal 5.6 only` [download] However you will find them all listed in the official docs here The key word you missed is perldelta :-) cheers tachyon	[reply] [d/l]

Have a look at `perldoc perldelta`. This will show you all changes from version to version. (No link to the monastery library, because it has only version 5.005)	[reply] [d/l]

Besides `perldoc perldelta`, I recommend the following perl.com article: What's New in Perl 5.6.0?, by Simon Cozens. -- Frag.	[reply]
