Could this be helpful?

Devs find it helpful. I do this in the dev builds of my implementation. I remove them from the minified build. Chrome has supported sourceURLs in Function for a long time now. I believe Firefox used to only support it in eval, when it used an @ instead of an #, so yay Firefox 36 for joining the Function sourceURL party.

Some have also found it useful to be able to set the sourceURL via a template option, {sourceURL: ...}, too.

Chrome gives you access to the eval'd VM instance and its line numbers anyways. What's the benefit of naming the instance?

I find it useful to have them in the sources view for a quick at-a-glance to make sure logic is right without having to instrument the code, even in the absence of a thrown error. Having the sourceURL configurable also allows organizing template sources which is nice.
