Are there any downsides to the Go language?

Go is a very popular language, but it has its drawbacks:

• Lack of generics in early versions made writing universal code more difficult. Although generics appeared in Go 1.18, they are not yet as flexible as in other languages.
• Limited support for OOP. Go does not have classes and inheritance, only composition and interfaces, which can be unusual.
• Minimal standard library. Sometimes, third-party libraries are needed for common tasks.
• No exceptions. Errors are handled explicitly, which increases code size and requires discipline.
• Less metaprogramming capabilities. No macros and reflection is limited.

These features make Go simple and predictable, but sometimes limit the flexibility and expressiveness of the code.
