I've want to capture every pair of letters in a string, but I can't seem to get it to work.

$_ = "blah";
my @matches = /(.(?=.))/g;
print "@matches\n";

I want it to print out "bl la ah", but, to capture the second level, I need to put another set of capturing parentheses within the lookahead. But, this puts the second character in $2, not $1 like I want to.

Help!

• 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).
