brute force but non-recursive:
my @data = qw( 000- 0101 011- 1-0-);
my @bin;
while (@data) {
my $data = shift @data;
if ($data =~ tr/-//) {
my ($zero, $one) = ($data, $data);
$zero =~ s/-/0/;
$one =~ s/-/1/;
unshift @data, $zero, $one;
}
else {
push @bin, $data;
}
}
print "@bin\n";
and anyway, what is your real problem? for a big subset of the ones I can imagine, maintaining your data as a list of numbers and masks can be a better solution than actually expanding the data set.

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).

are good places to start.
