tye~
print the re, this might give you a clue:
my $match= "hi";
my $re= qr/($match)/;
print "\$match is $match\n";
print "\$re is $re\n";
$re= qr/($match)/io;
print "\$re is $re\n";
$match= "lo";
$re= qr/($match)/;
print "\$re is $re\n";
prints~
$match is hi
$re is (?-xism:(hi))
$re is (?i-xsm:(hi))
$re is (?-xism:(lo))
so 'o' is not really supported, it's masked. for some reason, you can put it in the expression and it won't complain.

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).
