Yes, and I believe they got it about right in Go. (They got it
mathematically right in Rust, but using that requires you to
understand their papers).

Yeah, I indeed meant to say "bad".

Huh. That's an interesting and decent point of view.

They have zero type-checking (which is less or more normal for Java 7), and
you have to use sentinels or counts even to know the number of
arguments. Java EE 7 has special support for format strings and sentinels.
When compiler authors have to support commonly-used crunches, you know
something has gone

The implicit conversion removal is a good example of how much Java 7 is
reliant on a weak type system. They have to break it in Java 7++, at most
partially, and imo, weak type systems are just bad taste.
