Or, assuming a less ambiguous template format:
sub funpack {
my ($template, $source) = @_;
my %hash = map { reverse split /:/, $_, 2 } split " ", $template;
local $" = ' ';
@hash{keys %hash} = unpack "@{[ values %hash ]}", $source;
return \%hash;
}
my $data = funpack 'A20:name A1:sex A3:age A8:salary A12:sign', $foo;
(Field names may start with a digit with this data format. I also find it easier on the eye.)
Update: D'oh. Always test before posting.. Of course the above code doesn't preserve the order of fields, which is crucial.
sub funpack {
my ($template, $source) = @_;
my ($i, @field, @format) = 0;
push @{ (\@format, \@field)[$i++ & 1] }, $_
for map /^([^:]+):(.*)/, split " ", $template;
local $" = " ";
return { map +(shift(@format) => $_), unpack "@format", $source };
}
my $data = funpack 'A20:name A1:sex A3:age A8:salary A12:sign', $foo;
Makeshifts last the longest.

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).
