Easier than foreach $key (keys %links) loop

Well for some odd reason I thought I'd add this in. I've actually used it but its been in the back of my mind.

while(($key, $value) = each %Your_hash){
    print "$key contains the value: $value !";
}

The problem is that there's no place to insert a "sort" here. And if you abort the loop early, you run the risk of leaving the secret "each" pointer sitting somewhere in the middle of the hash, confusing the next such loop. So, "easier" is all relative. If this floats your boat, use it. -- Randal L. Schwartz, Perl hacker	[reply]
