First, there is no such requirement in the OP's original post and there is
no mention whether the output is going to be used for another processing
that requires character escaping. The correctness of a solution is judged
against its requirements.
Second, judging from the OP's question, it

Or you can do it manually:

I’d really like to see an example of generic code that takes both string and
numeric types that uses operators. Sorting/searching is one but as I already
said the built in string operators are not sufficient for collation cases.
Even generic code that “only works on unsigned types”.

All the ordering required is explicit in the representation. If x is an
argument of y, then x must come before y (in the eventual assembly output).
There is no other need for ordering within a basic block. Any order
consistent with the argument ordering I mentioned above is ok.

Operator overloading will never -- hopefully -- be implemented. It's a
perfect way to obscurate code. --Kent

I like the second draft for generics. It seems to me a large
simplification and improvement over the first draft. Considering just
the state of Go today, I would be quite happy with this, even if it's
not perfect. Thanks to Ian, Robert, and everyone else for their work
on this.
Also, I would vote
Hello gophers,
We have just released go1.15rc2, a release candidate version of Go 1.15.
It is cut from release-branch.go1.15 at the revision tagged go1.15rc2.
Please try your production load tests and unit tests with the new version.
Your help testing these pre-release versions is invaluable.

in my opinion, the values are like instructions, why can it be unordered?

Thank you guys, your tips were really helpful!
Here's the solution I came up with for reading the ECN bits:
After setting the IP_RECVTOS options
syscall.SetsockoptInt(int(fd), syscall.IPPROTO_IP, syscall.IP_RECVTOS, 1)
one can read packets from the socket using
n, oobn, flags, addr, err :=
To grow a slice, as a programmer you would do:
myslice = append(myslice, value)
myslice = append(myslice, anotherslice...)
Or you can do this my hand, by allocating a new slice of the required size,
and copying the elements you want to keep.
There is a great overview of how this works
Well, it says "lock_futex.go:152:2: ns declared but not used". An unused
variable is a compile error in Go.

I wanted to edit one file from the runtime library and build golang from
the source (golang version 1.10.4). Without modifying the source code, the
build process finished successfully passing all the tests., but after
modifying it, the following error appears.
Yeah, but my question is if it is possible to interpose the exported

Yeah, but my question if interposing this function is possible?

Yes, now `Test` is exported.

`test` is not exported. It would be, if it was called `Test` with a
capital `T`.

Hi,
I know from README that gollvm does not support race detector. Is there any
technical problem? Is it possible to use ThreadSanitizer in LLVM to
implement a workaround race detector in gollvm?
Thanks.
