Got this to filter out undefined values indirectly from a hash slice:
my %args = (profile => 'foo');
my %ta = %args{'profile', 'user', 'password'};
%ta = map { $_ => $args{$_} } grep { $args{$_ } } keys %ta;
It works well enough. But in trying to make it a little more concise:
my %args = (profile => 'foo');
%ta = map { $_ => $args{$_} } grep { $args{$_ } } keys %args{'profil
+e', 'user', 'password'};
you get an error: Experimental keys on scalar is now forbidden. Is there a good, more perlish way of pulling this off?

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).
