Hi

in a discussion how to efficiently hide a chunk of code (here org-mode syntax from emacs) in perlcode I came up with this "solution":

Using a here-doc to the next empty line in void context 

codeline();
 
<<;
* Headline
** [TODO] write test
** [DONE] documentation
 
codeline(); # last line was empty

[download]

This seems to be much shorter than if(0){..} constructs (which disallow '}' in the chunk) or POD (which needs plenty of empty lines) and can be easily extended to span empty lines by adding an explicit Here-doc-signaler or a variable to catch the chunk at runtime.

Anyway I get warnings because non-quoted Here-docs are deprecated so I need to switch to <<'';

Any other suggestions how to uncomment chunks?

Cheers Rolf
