[go-nuts] Why the default print prints to Stderr?

[Tong Sun]

Hi,

Why the default print prints to Stderr?

I had always assumed that without specific instruction, print will print to
stdout, but astonished to find out that it (the built-in print) will print
to Stderr.

Why is that?

Thanks

-----------------------
package main

func main() {
print("To StdOut?\n")
}
-----------------------

$ go run StdOut.go | wc
To StdOut?
0 0 0

$ go run StdOut.go 2>&1 | wc
1 2 11

This is as documented, see https://golang.org/pkg/builtin/#print

print and println are for debugging so stderr is more appropriate.
