The second argument is a variadic argument, so you can omit it; see
but i test this code it does not work!
Why??

In go when closure call the out varible will pass pointer to the closure
func so I doubt in example2.go y is passed &y to closure
I don't know the compile how to analysis this and decide that can be
allocated in stack correctly ?

Nice! Seems working!
I could not get Unix Domain Socket to work, since I expected an error on
Listen or Accept but there were no errors.

The runtime creates a new thread whenever there is a goroutine ready
to run and the number of currently running goroutines is less than
GOMAXPROCS.
Got some insight about this from Rog Peppe. The problem seems to step from
the fact that the String() method on http.Cookie does different things
based on what values are set in the cookie. If it's just Name and Value,
then String() returns a value suitable for a Cookie header (i.e. what you'd
Sorry, poor explanation again.
When a variable is used from outside a closure's scope, it is *captured* by
the closure. Usually that means that the closure function is modified to
include a reference to that variable when it is called as a regular
function. An example from the compiler:
https://gi
That is... awesome...

You didn't say how it doesn't work. You need to ask good questions to get
good answers.

Glad you think so :) Suggestions and bugs welcome. It's under active
development, and I know some things don't work right now (like variadic
functions), but I'd like to make it work with as wide a swath of go
functions as I can :) And I think that, since there's such a strong
culture of bein

To see the escape analysis results, compile with -gcflags "-m -m -m -m".
The code in each of the example should be relatively similar, which is why
it is a bug that one of them causes the variable to escape to the heap.

They're not URLs. They're Go import paths.
To make them into links, prefix them with https://godoc.org/ like

Works fine when I tested it using this approach:
https://play.golang.org/p/A1C5BEIP2G
func main() {
Stick an @ at the start of the file name, or the socket will remain on disk
after the process has exited.

That's even better, and doesn't need to use the Remove().
I didn't see it documented about using @ for abstract socket. Did I miss
that
package main
import (
"fmt"
_ "net/http/pprof"
"testing"
)
// 8 Bytes/op 1 allocs/op
func BenchmarkFmt1(b *testing.B) {
b.ReportAllocs()
for i := 0; i < b.N; i++ {
fmt.Println(100)
}
}
// 16 Bytes/op 1 allocs/op
func BenchmarkFmt2(b *testing.B) {
b.Re
It's a Linux thing, Google abstract domain socket.
