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!

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
