Not really- I changed that in the source and the Syntax was fine from that point on. It's the // that causes the trouble here. 
Im User to work with ultraedit and textwrangler which both Support this feature. I've been using this the last ten years and needed this for my iPad aswell.

it makes the whole workflow far less complicated as I'm won't need to think about which is the latest source! This would help me a lot instead of first downloading and the upload it again. 
Got the Same with PERL here...

$vRow =~ s/\!FOLDER_ID\!//cg;

after this line, no more Syntax is recognized :)
