Re: Passing Any Range of Values to a Sub

Hi there.

I'm also a student learning the language.

Personally, I think it's best to always use:

my $size = scalar(@testarr);

rather than:

my $size = @testarr;

Because it's easier to understand and by naming something you exert a little more control over it. It also helps stress the difference between scalars and arrays, which is helpful for me as a student.

I'd be interested in knowing what the more established users of the language think about using scalar() rather than using only the array.

Any comments?

If it's clearer for you and the people you work with, go ahead and use it. Maintainability and clear communication trump just about any other concern. I personally don't care for it because I'm used to context. It's effectively a no-op, and, if I don't have to worry about the maintainability burden to someone who doesn't have a firm grip on context (and I usually don't), I prefer to leave out unnecessary code. You'll probably find yourself using it less and less often as you continue learning.	[reply]

That makes sense, thanks a lot! I'd prefer to send a message like this privately, but I don't think I can do that. If there's a way of sending PMs here, someone please send me one and let me know!! :) *Update: to send someone a private message, just type /msg username message* in the chatter box and hit "talk".** --Dave	[reply]
