I believe I am in the minority here, but I am not a singleton minority.
There are at least several of us who agree that «var» should be used
over «:=» whenever

To add to this issue, that's a problem that is also related to how type
equality is treated in the spec and deep equality. If we have some kind of
"snapshot" slices for instance, an equality can be determined for these
(with some other things to consider) and for structs with fields that are
"s
I get that we can do that but it's not strictly about slices operations
such as appending or copying.
Of course, we could copy slices all the time but then there is no benefit
in having them and it is not ergonomic as your example shows, nor does it
fit your performance cost requirements.

Correct, so basically avoid x := y[i:j] if you actually meant copy
https://golang.org/ref/spec#Appending_and_copying_slices
var a = [...]int{0, 1, 2, 3, 4, 5, 6, 7}
var s = make([]int, 6)
var b = make([]byte, 5)
n1 := copy(s, a[0:])// n1 == 6, s == []int{0, 1, 2, 3, 4, 5}
n2 := copy(s
It could be done, Robert. Then the programs would run in every platform
that Go runs, quite a few!

Feel free to classify the tool anyway you like, Anca.
I don't buy the distinction between "compiler" and "transpiler" because
it's the same thing. They read code in some language and generates code in
some language.
I picked C for output because it is utterly portable and everyone could
enjoy
I just edited the project README to clarify this point. This tool generates
C code that you submits to the C compiler for your particular platform.

Hi, Anca.
The compiler proper doesn't use C code, generated code does, it has
references to some support functions.
Those support functions are declared in basiclib.h and defined in
basiclib.c .

Hi,
Thank you for the response.
My issue is not really about append but can be illustrated by this :

Sorry, the performance cost is to high. But you can practice a few
programming habits that can prevent this, like use x = append(x, y) and
never x = append(y, x) Basically we only need a Go proverb bible mentioned
in one of Rob Pike's talks and we will be fine :)

There is an important distinction:
- users of your project / library are interested in hard dependencies of it
- developers / testers of your library will actually be using its test
dependencies
Go modules enforces the first group your test dependencies as hard
dependencies, which is not right.

Hello,
I've just realized that slices were much more delicate to use than
initially thought. The main issue is that when slices share the same
backing array, it is too easy to inadvertently have an unprotected
concurrent Read/Write if one is not careful.
That can easily happen for a struct tha

Can I assume every output of go vet passes through here? So basically need
to figure out all the references to this two functions and change the
format?
