Your indices function sounds sorta like the smart match code that I heard theDamian talk about at his Perl6 talk -- well, at least knowing whether "heimer" is in the list.
Of course, you could write your own indices() function pretty quickly, using a sort of modification of the Schwartzian Transform (I actually have tested this, on a few cases, but let me know if I've missed anything):
sub indices ($@) {
# note the prototype has target, then list
my $target = shift;
my (@list) = @_;
my $index = 0;
map { $_->[1] }
grep { $_->[0] eq $target }
map { [$_ , $index++] } @list;
}
I'm sure some wizard out there could tighten this up, but I think it's pretty clear what I'm aiming at.

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).
