I use this feature from time to time, but not usually intentionally. I appreciate that it doesn't force me to rearrange a bunch of parameters at call sites just because I happen to change the order of them in the function declaration, though.

This special case adds complexity to the language, and runs against our general trend of treating argument labels as a significant part of an API's name, and preferring a single way of writing API calls. I think it's worth revisiting this design choice—is the special case worth the complexity? How many people take advantage of default argument reordering?
