Well, that's definitely more of a PHP approach to things, and I think
the original implementation was focussed much more on a traditional
mechanism for formatting arguments.

I don't think there's anything wrong necessarily with that approach
per se. I would recommend writing some tests for the function if you
decide to write a patch for that feature.
