Nodejs: How to set the file name for eval?

Question

Background: I developed a small module system for node.js that asynchronously loads all required code from a separate source server and compiles it with eval(code). My problem is that for all run-time errors in such "eval-ed" code, the stack trace shows <anonymous> as the file name --- I cannot distinguish which code piece is referred to.

My question: Is there a way to set the file-name for eval so that the stack trace shows some program-defined string instead of <anonymous>?

My current (imperfect) solution: As of now, I write the code to a file and load it with require(file). This will sow the file name --- but it is a complicated workaround.

Note: Normally, the run-time errors do not show up at the compilation of the eval call, but later, when the compiled code is used. Thus, try/catch around the eval does not help to identify which code piece failed.

Eventually, this new feature of the V8 engine will make its way to Node.js:

Issue 2948: Support //# sourceURL= and //# sourceMappingURL= in v8's parser

This method works for Browsers currently.
