my %hash = map { $_->[0] => { key1 => $_->[1],
key2 => alter($_->[1]) } }
map { [ $_ => 'longstring'.$_.'more' ] }

}
or (using auto-vivification)

$hash{$_}{key2} = alter($foo);
}

foreach my $key (@list) {
foreach ('longstring'.$key.'more') {

or (in two steps)
my %hash = map { $_ => { key1 => 'longstring'.$_.'more' } }
@list;

Updated: Added more alternatives.
Updated: Fixed bug. Changed $_ to $key in the concatenation in later snippets.

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).
