Too bad they don't include range datatypes, à la Ada, where you can state "x is a number in [3;17]". Those exist since the 1970s. I can't imagine how one can ever write a program without range datatypes. Oh, I need self-modifying code and both computed and assigned gotos, too. I'm used to using them since FORTRAN. Come on, Go team, fix your language so that we can start using it.
