func before function

[valent...@gmail.com]

Why is it necessary to write func in go before declaring a function; if in C, when parsing a function, there is no such need?
Why "func sum(a, b int) int {...}" can't be "sum(a, b int) int {...}"

Of course it could be like that. But why should it be

like that? Is there any benefit? Did you think it through?

How about methods and function literals? Is the grammer

still non-ambiguous?

may be that's the way compiler understand where new function start
