This reminds me of a trick to get multiline strings in javascript before they where formally introduced. If you coerce a function in to a string you get the source code for that function, comments and all. This meant that you could write a function with multiline comments and then pick out the middle part. Haven’t tested it so it’s probably sligthly wrong but it was something like:

var multiLine = ('' + function () {/*
line 1
line 2
*/});
multiLine = multiLine.substring(16, subString.length-4);
