I was reading through the new Perl Cookbook, particularly the Arrays chapter. I noticed the author states you must use the scalar function to find the count of elements in an array. Is this something that has changed? I've used code like this all over the place...
@foo = ( 'foo', 'bar' );
print "There are " . @foo . " elements in foo.\n";
...and it works. Is there a pitfall I'm missing? This threw me a little since I don't use the scalar function unless I have to. Is there a problem here or has what the author stated changed in the current version of perl. I'm using Mandrake Linux with perl 5.8.0. It's not a huge deal, but I want to make sure I change some of the places I've used it like the way above before I fall into the pitfall.
