I genuinely have no idea what you're referring to by "stringly-typing all over stdlib". I've written Go every day for the better part of a decade and used the standard library the whole time. What standard library functions require passing in the string of a type?

Struct tags is the most notorious example.

They’re convenient but error-prone. I think everyone who wrote a decent amount of Go had that malformed, misspelled, or misnamed (“db” vs “sql”) tag at some point.

You are right, stdlib doesn't have much of stringly-typing.

However the core language way of dealing with enums for example is extremely weak. It's common to have a typed enum on a struct. When parsing the struct, random string (or whatever the alias is) values sneak in and the only thing you can do is validate.

We're literally in the comment thread of a new stringly typed thing being introduced to the stdlib!
