Golang build Error:syntax error:nested func not allowed

A simple Web program was written in the Notebook, but the compilation failed with the hint "syntax error:nested func not allowed".

Do not understand what the meaning, fortunately, the code is small, the original method is the end of the "}" lost !

Package Mainimport"FMT"Import"net/http"Func Main () {http. Handlefunc ("/", hello) Err:= http. Listenandserve (": 8080", nil)ifErr! =Nil {fmt. PRINTLN (Err)}}func Hello (rw http. Responsewriter, R*http. Request) {fmt. fprintf (rw,"Hello Lao Yu!\n")}

After adding the missing "}", the compilation passes!

What is the error message that prompts you? The original is to tell " do not allow function nesting ".

Okay, just this record has an error.
