IPv6 addresses including a zone identifier [rfc4007] are not parsed

Atan is implemented in assembly. for amd64 it's just a call to atan
(lowercase a): https://golang.org/src/math/atan_amd64.s
for 386 it is not: https://golang.org/src/math/atan_386.s

Go appears to be trademarked, as well as the new design of the Go
logo. Golang doesn't seem to be.
file an issue, please, if you have not done so already. i'd like to follow it.

when you terminate a process the virtual memory associated with that
process ceases to exist. any real memory associated with that process
is not addressable anymore. if another process allocates a page that
maps to a page previously held by the first process will get a
zeroed-out page.

macOS doesn't support static linking user binaries. in fact I do see
libSystem linked for each go binary on my Mojave system, including the
simplest non-outputting hello world:

package main; func main(){}
$ go build t.go && otool -L t

once you have done this you should be able to cd to
E:\temp\go-build828919622 and look around to see if any files have

is this a school or work computer? if yes then a group policy may have
disabled the execution of exe files. supply the "-work" argument to go
build. it will
try setting GOTMPDIR. not sure what this corresponds to on windows,
but it will change where the go tool will create its temp files:
$ go run -x t.go
WORK=/var/folders/sp/06p28g2d0vs7gd2vhf26wl9mgn/T/go-build126372523
[...]
$ GOTMPDIR=/tmp/go go run -x t.go
WORK=/tmp/go/go-build661115935

not the first time this has come up. here are a couple of references:

The author of the PR was most likely working on Go's tip (what will
become 1.13), where the requirement that the right operator in a shift
is an unsigned integer has been lifted.
Please do! We need to resolve this connundrum for the next 5
generations of computer programmers!

Here's the lore associated with the subject: Ken wanted ternary, Rob
and Robert did not. They overruled Ken (remember, early on all three
had to agree for a feature to go in). The end.
The number of frivolous and egregious abuse of ternary that I've seen
in _modern_ C code is too high.jpg

I believe the Go team considered this very carefully early on the
language's development and came to the decision to use "if test" for
"? (test)" and "} else {" for "}{" (without the implied newline). They
also threw in "} else i
