Add line numbers to hereis blocks that contain perl source code
EvalLineNumbers adds a #line “this-file” 392 comment to hereis text that is going to be eval’d so that error messages will point back to the right place.
Please note when you embed \n in your code, it gets expanded in double-quote hereis documents so it will mess up your line numbering. Use \n instead when you can.
