Unfortunately, you can't use /* */ inline like you can with php. /* can only be used at the start of the line and you can't put a */ inline, either. Maybe that should be changed and leave pipes as they are?
Not a good plan:
/* Comment starts here
echo -a code commented out
echo -a $regex($1, /hello .*/)
Comment ends here */
"
damn why is my code creating errors?"
Quoteless strings + abitrary syntax rules = bugs
