ii := new(int)
(*ii) = 3
(*ii)++
Yes, it's not exactly the same syntax. It still demonstrates that what you
are suggesting creates, at best, very marginal benefit.

I did. why there are always people assuming the other party they are
talking to is just silly.
Anyway, this is what i got:
var ii *int
ii = 3
ii++
cannot use 3 (type int) as type *int in assignment
invalid operation: ii++ (non-numeric type *int)

I don't think it's immediately obvious what use cases this "int?" proposal
delivers that aren't covered by "*int". The encoding/json package uses
pointers to support null JSON values.
As a more general point, when someone answers your question, they're taking
time out of their day to help you. I t
Hi guys,
I am learning golang with the fantastic book "Go in Action". And I have
some problems with understanding when to switch a goroutine to be run in
chapter 6.

Greetings,
I have been tracking the recent changes taking place on the Go master
branch as we come up on a 1.9 official release. A couple times a week I
would refresh my local Go repo with the following command:
$ git pull origin master
Then, after my local repo update completes:
$ cd src
$ e
Thanks Nate,

Hey guys, sorry for bothering :D
Here I want to ask a small question about the Golang binary debug info.
The steps to reproduce my problem:
1. $ cat symtab.go
```
package main
import (
"fmt"
"net/http"
_ "net/http/pprof"
"os"
)
func main() {
fmt.Println(os.Getpid())
http.ListenAndServe(":9990
Go can do what you want today, just that it's spelled "*int".

Hi
I have a golang HTTP server that I am deploying on an AWS EC2 VM, as a
systemd service.
Right now, I am manually deploying the service as follows:
1) vm$ sudo systemctl stop
2) dev$ scp
3)psql$ Apply migrations manually
4) vm$ sudo stystemctl start
4) vm$ sudo stystemctl status ;# Ju
Awesome, thanks!
I just can't match "arbitrary precision" and "float" expressions: 1/3 is
rational, but can't be represented with float-like data structure.
The same problem is with arbitrary precision uint: what will ^uint-1 be?
So, arbitrary precision int and user-specified-precision float is g
Jimmy, thank you for the tip! i went there and added my modest suggestions
to the proposal.

Tamás, you make a very important point. It is one that GRI did a very good
job of in big.Float. The question of how to specify precision for
variable-precision floa
What is an arbitrary precision float? 1/3, Pi, ✓2 ?

There's https://github.com/golang/go/issues/19623 for making int
arbitrary precision in Go2 (yes, please) there could also be an
arbitrary precision float to go with float32/float64 :D

- As int is not a pointer type, what would nil int mean?
- Are you willing to sacrifice extra storage for the additional isNil
information or do you prefer that int cannot r
sql.NullInt64 or alike with custom MarshalJSON and UnmarshalJSON?

For mo
Suggesting C# type syntax like "int*?*" so as to take nil as valid value.
Currently:
var i int
i = nil
will give:
cannot use nil as type int in assignment
However, more and more people are using json to transport data, and there
will be times that json may be invalid. I.e., the "int" type ha
I would REALLY like to see big types as normal declarations and syntax. The
SSA framework seems suitable to automatically manage the temporaries.
