I got an interesting response about this subject from Rafael Garcia-Suarez about this, he said it was ok to post it so here goes...
You can mess with the internals : something like
use B qw/class svref_2object/;
sub is_a_precompiled_regexp {
my $r = shift;
return 0 unless ref $r;
my $o = svref_2object $r;
return (class($o) eq "PVMG") && ($o->MAGIC->TYPE eq 'r') ? 1 : 0;
}
Without looking at the internals, I don't have an answer.
Thanks Rafael!

Writing a good benchmark isnt as easy as it might look.

Are you posting in the right place? Check out Where do I post X? to know for sure.

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).

Want more info? How to link
or How to display code and escape characters
are good places to start.
