Ruby或等于的golang版本|| =

Out of curiosity, what would be the idiomatic way to assign a variable if it's nil in go?

I'm looking for something similar to ruby's foo ||= bar

Is there a shorter version of this?

if foo == nil{  
  foo = bar
}

    Your version is already the simplest, shortest and idiomatic way to do it.
