That was simply based on this, perhaps prior to 1.0?: "https://groups.google.com/forum/#!searchin/golang-nuts/make$20new$20zeroed|sort:date/golang-nuts/793ZF_yeqbk/norrWEAyVTcJ" "we have both make and new mainly for pragmatic reasons. new(T) returns *T. so it can't return chan int, which doesn't have the form *T. so another operator is needed. for a short time, we tried getting by with just make, and make(*T) was like new(T) is today. people found it too surprising coming from c, c++, and java. russ" On reflection, I guess the subject line is inaccurate. When I find the time I will suggest a patch for the tour. I Just wondered if it may be a cause of list noise, but probably not. I just created noise instead, ;) Regards, KC -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.

Re: [go-nuts] Could the go Tour be clearer on WHY recent make := zeroes
(I forgot in my previous message: the email subject seems to imply that := or make() was changed since 1.0. No it wasn't.) This for later reference: new and make and initialization is very easy to parse in the faq in the spec and in the effective go document: https://golang.org/doc/faq#new_and_make I'm not sure about the tour recommendation change, if you are curious I recommend you to file an issue, to see what others with commit rights think about the change.

I was prompted by atleast a couple of books but also the spec. Indeed the spec is clearer than I realised, had I clicked through on the link you sent "initial values", here. https://golang.org/ref/spec#Allocation Perhaps the tour could link to that section of the spec? https://tour.golang.org/moretypes/13 "allocates a zeroed array" -> "https://golang.org/ref/spec#The_zero_value; -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.

[go-nuts] Could the go Tour be clearer on WHY recent make := zeroes
Hi "https://tour.golang.org/moretypes/13; "The make function allocates a zeroed array and returns a slice that refers to that array." Yet more detailed literature states that make does not zero whilst new does. I gather this is because the shorthand used in the tour, instantiates new in the background and wants to be as simple as possible for new users? I am not sure if that is actually most helpful. To avoid confusion, should it be something like: The shorthand make := syntax allocates a zeroed array (akin to automatically invoking new) and returns a slice that refers to that array?
