This is related to https://golang.org/doc/faq#closures_and_goroutines . But in general in a range loop the value is copied from the range source to the loop variable. Your sample code seems to think that the loop variable is a reference to the slice element, but it's not; it's a copy. It's not surprising that the address of that copy, the loop variable v, is always the same. Ian -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
