Re: Passing arrays and references to arrays

I'm a little fuzzy on the first one - is it assigning an anonymous array to element 0 of @choices, or is something else going on?

i think so, too. but if you don't trust yourself, go on and use Data::Dumper to find out.
i don't see a difference between these three techniques from the called funktion point of view. however, i would do this a bit different:

my $choices = [qw/one two three four/];
my $me = $mw->MatchEntry(-choices => $choices);
[download]

or did i miss some obvious reason why that wouldn't work?

It does work. Variant number 4 :). Guess I was array fixated by the first two variants. Perl is Huffman encoded by design.	[reply]

If I understand everything correctly then I don't think this is a fourth variant: `\@$choices` [download] compared to `$choices` [download] I think you need to look up array refs and pay particular attention to referencing and dereferencing. In both cases you have an array ref, however in the first you deref it only to then make it a reference again. The second doesn't do this unneccessary merry go round. HTH.	[reply] [d/l] [select]
