OK, then I think you've answered your own question; your uses should
handle the nils, rather than papering over them by assigning a pointer
to "".
If you expect to have "" when the value is empty, just use string.

This is not nice if you want to reuse the slice, and still may leak the
fields.

StringChan and StringSendingChan are named types and so you will need a
conversion. It would be easier though to just not declare types here.

If you only need the map conditionally, you need to declare it and then
conditionally make it.

Say I have a []T that I want to use as a common stem that has a tail
appended onto it, used concurrently, for example:

Why would you return a newly allocated [c]byte pointer in fooSTUPID
instead of nil? That is *not* doing what is suggested, but rather
returning a more likely valid and usable value.
We (gonum) would extend the security exception to include scientific
code; there are far too many peer reviewed works that depend on code
that will blithely continue after an error condition that should stop
execution or log failure. These can and do end up contributing to costs

This is done with the -c flag. It will leave a -test binary

We'd (gonum-dev) likely advise not to use julia for reasons that I
won't go into here.
However, I can suggest that the OP checks out the data-science channel

You could try it this way if you really need a separate function.

This looks like a QEMU thing more than a Go thing.

Do you have any reason to believe that it's not QEMU (have you done
this on real hardware)? It has past form for this kind of problem.
I have just tried to replicate this on a pi and both 1.11.5 and 1.11.9
complete successfully.
BTW 1.11 is not the the current release and for 1.11, the most recen

I also.
We have to add additional mess to our build scripts when we get testing
dependencies that are not part of our distribution to avoid
contaminating the go.{mod,sum} in the repo root.
This has repeatedly been a source of irritation and frustration.

Any particular reason for that? Neither is safer than the other and
it's not clear to me that you can actually achieve the goal of having a
compile-time check for the correctness of this type of conversion.

Have you ever considered using Go as the configuration format for your
project? Have you wondered whether you need a Turing complete
configuration language?
Of course not; here it is: https://github.com/kortschak/yaegiconf
Appalled? OK.

I am looking at some changes we have made to make code generation
independent of GOPATH since from the SettingGOPATH page of the wiki
says "If no GOPATH is set, it is assumed to be $HOME/go on Unix systems
and %USERPROFILE%\go on Windows."
However, when I run `go env` I see `missing $GOPATH` in re
Yes, that explains it. Perhaps the error could be more informative.

Over 10 years ago Gustavo Niemeyer invented the geohash geographic
hashing system https://en.wikipedia.org/wiki/Geohash for clearly and
concisely representing geographic locations at arbitrary precision.
Now, here is geocrypt, a package that returns or checks a cryptographic
hash of a geolocation.
