Idiomatic way to do conversion/type assertion on multiple return values in Go

Question

What is the idiomatic way to cast multiple return values in Go?

Can you do it in a single line, or do you need to use temporary variables such as I\'ve done in my exampl

Answer 1

Or just in a single if:

if v, ok := value.(migrater); ok {
    v.migrate()
}

Go will take care of the cast inside the if clause and let you access the properties of the casted type.
