Unless I misunderstand what you're asking for; you can do the
assignment multiple times with
different values:
$text = sub {
<<EOT;
Dear $person,
I know that this text is $adjective.
But I wish it could be...
EOT
};
my @subs=('Mom:not interpolates',
'Dad:maybe interpolated',
'Sis:who knows');
foreach (@subs){
local ($person,$adjevtive)=split ':',$_;
print &$text;
}
My technique will also
work for your number example (with everything
stored as a function). However it look slightly ugly:
$n = sub {1};
$m = sub {&$n*2};
$o = sub {&$m*2};
$s = sub {&$n." ".&$m." ".&$o."\n"};
print &$s;
$n = sub {2};
print &$s;

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).
