Good is _really_ subjective. While its definitely better than JS/Node it has some warts. For example, I find the "time" builtin package to be pretty terrible. Specifically how it does formatting[0]. This method makes the format look like a magic string rather than being an obvious template like other languages would use.

I've found some legitimate bugs[1] in simple functions that don't give me a ton of confidence in it either.

Personally I find the standard libraries in the likes of Python and .NET Core much more comprehensive, intuitive, and reliable.
