> The ability to quickly refactor code is very important and Go fails at it horribly for a number of reasons. 1) sheer verbosity. 2) multiple return makes altering function signatures tedious. 3) no generics mean code is written in hard to refactor styles out of the box 4) poor reflection support 5) poor tooling compared to professional grade languages (Java/C#/etc)

1) there are worse languages in that category. some are even more widely used.

2) that doesn't make sense. return arguments are part of the argument list signature. either changing any argument makes this tedious, or none does. you indicated that only return ones do for some reason.

3) can't argue there. in the rare occasion that type asserting interfaces is required because of lack of generics, things really do suck.

4) can you elaborate on that?

5) only thing i found lacking was absence of advanced refactoring tools. for everything else, the available tooling seems to be on part with what i've used with java (anecdotal)
