Just wanted to get some opinions on this particular method of calling subroutines with arguments
my ($ret, $msg) = mysub(
'cat' => $val1,
'dog' => $val2
);
sub mysub {
my $args = {
'cat' => undef,
'dog' => undef,
@_
};
my $cat = $args->{'cat'};
my $dog = $args->{'dog'};
# do something with them
if ($ok) {
return($answer, undef);
} else {
return(undef, $error_msg);
}
}
Sort of like a poor man's prototyping?
At least I think it's better than "shift"ing to get arguments, etc. Everyone tell me if I am wrong, please!
What does this little button do . .<Click>;

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.
