Re: if

Is there any reason you are dereferencing your ref hash with a hash slice of one element?

  @{$ref}{qw/URL/}
[download]

is just a convoluted way of saying:

  $ref->{URL}
[download]

There may be some tricks to be played by returning a singleton list instead of a scalar, but I don't think you're looking for anything of that sort.

I swear there's a book somewhere teaching people a Bondage and Discipline version of Perl. This convoluted access syntax has shown up time after time in posts. Instead, make it all cute and fluffy with curly braces: `@{${ref}}{map{qw{URL}}}` Just kidding	[reply] [d/l]

i knew that, and the code started out that way, but at a certain point i decided to leave it open for more than one field in each print line. but it doesn't make sense to me now and i just went in and changed them all. thanks.	[reply]
