this is the go package for pfn, i made it a package for using it with the pfn-play repo, which is a version of the language running on the web.
if you, for any weird reason, need to use pfn in your go code, just type
$ go get github.com/TsukiGva2/pfn
in your project's folder, and try transpiling a simple script with the following code:
import "github.com/TsukiGva2/pfn"
func main() {
pfn.Run(".f(|x|->0)", true) // true is for printing the output to the console
}
