Yes. It can be simplified with help of copy() to this: https://play.golang.org/p/AsS7RaOPwOm Also there are 3rd-party packages for making "deep copy", but my guess is they will be less effective in your use case. In case you mostly need to change just one value then you may consider avoid copying slices which won't be modified, i.e. create function to change one value and have it copy just one modified slice (plus parent slice, of course). -- WBR, Alex. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
