Of course. If the main cornerstone of your project is map it's probably not the greatest idea to use Go, but if you're using Go for other reasons and happen to need a quick map function there's no reason to change languages just because Go doesn't have a standard library implementation

But then it's pretty odd to use Go because you like the language, while not being able to design a proper map().

And map() btw is only the tip of the iceberg in functional programming. But then again, Go is not a functional programming language.
