An old school guy like me love statically typed language, even I tasted the convenience of dynamic typed languages for handling data with complex structure like JSON or operating data with SQL/NoSQL. The statically typed language avoids many ambiguous issues and let us figure out the mistake before before unit test reports it. So I love Go in many pieces, it leverages many concepts from other languages, has a easy understanding struct types, great tool set for production…etc, and most importantly, it’s easy to write and performance will not let you down, but I also got confused sometimes and found many ambiguous parts in Go.

This would bump up the paper one line, whatever that was, but not move the write head. If you did abc\ndef, the teletype would print abc def \r is “carriage return”. This would cause the write head to return to its leftmost position.
