Hi y'all,
given that the concern here seems to be performance (though, TBH, I doubt
this particular case is much of a bottleneck), this seems to be far simpler
to address as a compiler optimization - if the compiler can prove there are
no other references to a `[]byte`, it can do the conversion
There is a prerequisite to transfer ownership: it must be proved that
no other values share ownership of the byte slice returned by
ioutil.ReadFile.

Is it good to introduce owner transfer based string<->[]byte conversions?
After the conversion, the being converted string/[]byte values mustn't be
used any more.
Such as
tlsCertData, _ = ioutil.ReadFile("/etc/ssl/mycert")
var tlsCert string = bultin.ByteSlice2String(tlsCertData)
// forbid

Ok. I figured it might save an allocation as well if the coder made clear their

I apologise if this has already been discussed. Google didn't turn up anything
directly related.
If you read a file using the following that returns a byte slice.
tlsCertb, err := ioutil.ReadFile("/etc/ssl/mycert")
if err != nil {
log.Fatal(err)
}
tlsCert = string(tlsCertb)
Is there a way to
