Hi Monks,
This tiny code fails with "Can't use an undefined value as an ARRAY reference" exception.
use strict;
use warnings;
use diagnostics;
my $href = {
list => undef,
};
my @a = @{$href->{list}}; # fails here
foreach my $i (@a) {
print "$i\n";
}
but this one works as expected (does nothing)
use strict;
use warnings;
use diagnostics;
my $href = {
list => undef,
};
foreach my $i (@{$href->{list}}) {
print "$i\n";
}
Could you explain me what makes the difference here? Thanks.
My perl is 5.18.2.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
