Ah, I see, I was worried that you were having a problem with tangling.
Maybe there is some way to hide the org-mode wrappings with "heredoc"
style lines (I'm not very familiar with perl, but I hear it is very
flexible about the syntax in source-code files).  Maybe something like

  =for comment

  org-mode text

  * headlines

  etc...

  #+begin_src perl
  =cut

  =for comment
  #+end_src

  more org-mode...

Certainly tangling is an extra step, and as a matter of taste not
something many people will want to use, but I wouldn't say it's
dangerous.  I tangle in a couple of very real very large single-language
projects (sometimes with the same code tangling to run on different
platforms) and find it reliable.

Good luck, if you find a workable solution, I'm sure there'd be interest
to hear about it here.
