Hah! I finally understood something! Probably something I shd have understood a while ago... namely that a hash in array context is an array. So When I do

@list = qw (one two three);
%args = ( arg1 => 'string', arg2 => 5, arg3 => \@list );

sub1(%args);

sub sub1 {
    print "$_\n" for @_;
}

I get

arg1
string
arg2
5
arg3
ARRAY(0x17656b4)

Obvious when you think about it. I mention it here more to fix it in my own mind than in the faint hope of enlightening others, who are probably way ahead of me. But it does make sense for me of a lot of stuff I've been doing on trust, not 100% knowing why it works... like this way of passing arguments to HTML::Template.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• 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).
