Resending to the mailing list as that was my intention but I errored again. Did the gmail UI changed again?

This is the most strange claim I have read about Go ever. You *must* read the language spec to understand what any programming language does. You *cannot* just guess because "other languages" do somethíng or use similar approaches and then be surprised you have guessed wrong. And as can be seen often, blame the language designers they didn't meet your unfounded expectations. What bothers me personally about the proposal and why I think it's a bad idea: The semantics will be defined by metadata. Any Go code snippet with such a loop, existing or future, all over the Internet/books/blogs, ... will become ambiguous in what it does without those metadata, which are not usually/always available alongside. You can say "other languages have that problem as well, see the different C, Perl, Python, you name it... versions". And you would be right. The point is that the Go 1 compatibility promise gave us the nice property of Go not suffering from such problems. I oppose the idea of introducing such a problem into the language voluntarily, 10+ years later. Maybe it would be better to bite the bullet, introduce Go 2 and embrace the shizma. /s -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
