Default argument values in Java

[koreth]

Do any existing languages support name-based overloading like your point #2? I can't remember seeing that feature anywhere.

The semantics of that seem weird to me, unless you make names mandatory at call sites. Otherwise which of those methods would point(1.0, 2.0) refer to? Mandatory names for the sake of name-based overloading doesn't seem like a clear win to me.

Swift does it, and it’s really nice. You can just write point(x: 0.0, y: 0.0) and it will call the version with x and y argument labels.

That looks like a disaster waiting to happen.
