You can still do the same thing using lexicals (if you are allergic to using symbol-table variables). The only thing to be careful is to reuse the same push statement and same target array every time. This is adapted from the code in Re^3: Regexes: finding ALL matches (including overlap):
{
my @matches;
my $push = qr/(?{ push @matches, $1 })/;
sub match_all_ways {
my ($string, $regex) = @_;
@matches = ();
$string =~ m/($regex)$push(?!)/;
return @matches;
}
}
print match_all_ways( "TXXXABCDGXXXCCCDTGYYYCCCYYYCC", qr/XXX.*YYY/ );
Technically, $push is not needed -- you could just include (?{push @matches, $1}) in the m// statement inline. However, I like this way as it makes it a much more obvious that this part of the regex is only compiled once.

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).
