Go programming language bracket pair style

Question

I only recently learned Go when I try my first world hello of this style:

func main() { ...somemagic... } 

and the 6g compiler says this is wrong.

But with this style:

 func main(){ ...somemagic... } 

This is normal.

Is the first style of a pair of parentheses illegal in Go?

Answer 1

Yes. This is the result of an automatic semicolon in Go.

By the way, Go developers will format their code using gofmt and follow this formatting.

Answer 2

Yes, the first form cannot work due to insertion rules with a comma .
