Re: Re: Re: Hashes and Functions

IMHO, "shift" is the better way to get arguments off of @_. If you start using "shift", you'll never get confused about scalar vs. list context, etc.

So,

     my ($cref, $dref) = @_;
[download]

becomes

     my $cref = shift;
     my $dref = shift;
[download]

Very clean, very easy. No confusion :-)

HTH.

Uhhh ... I disagree. It may be cleaner, but I don't think that this style will keep you learning. I believe it is better to directly confront the syntactic issues you have and learn from them than try to avoid them. For example, by pushing my$self into confronting list vs. scalar context, I learned more about what context really is. That allows me to take advantage of nifty features like wantarray. ------ We are the carpenters and bricklayers of the Information Age. Don't go borrowing trouble.
