My 2 cents. I'm a seasoned Go programmer with years of professional Go
experience, and decades of coding work.
Personally, I would avoid goto if possible. It may "have been a best
practice for a long time" in C/C++ and other languages. But in Go there are
usually better ways to write code. The are situations where a goto for exit
cleanup is the clearest solution, but I recently worked on a 50k line
project where we only did it once.
Another, a personal preference - I dislike bare returns in most situations.
I know I am not alone in this opinion. Specifying the return values
explicitly is just clearer, avoids a class of bugs, and can make reading
the code quicker and easier.
func ret2(b bool) (int, int) {
if b {
return 1, 2
}
return 2, 3
}
Or
func ret2(b bool) (x, y int) {x=1
y=2
if b {
return
} else {
x,y = 2, 3
return
