One way to "reset" the flip-flop is to recompile its statement.
use strict;
my @a = qw(hubba bubba abba zappa);
print blah("bubba", @a), "\n";
print blah("bubba", @a), "\n";
sub blah {
my($look_for, @array)=@_;
my @elements_we_want;
my $string =
'(undef, @elements_we_want) = grep { $_ eq $look_for .. 1 } @a
+rray;';
eval $string;
return @elements_we_want;
}
Edit: Sorry, I did not notice the similiar idea by JavaFan.

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).

or How to display code and escape characters
are good places to start.
