md5 hash is an array type and can be used as a map key directly:

Well, in my case I don't want to convert the []byte to hexadecimal string,
because it uses 2x more memory.
The code contains a huge map where the key is an MD5 hash.
Please note that I'm not personally working on this.
I was reviewing the code written by a coworker, and I noticed that there

I always thought that the C style format strings were unreadable and the hex
package methods were much clearer, personally.

Printf can print hexadecimal just fine. Never understood the point of

Meanwhile, for questions about strings, see blog.golang.org/strings.

I personally wouldn't do this. If you're going to incur the overhead of a heap
allocation, might as well incur a bit more and encode the hash, eg. using
hex.EncodeToString [1], just so that you don't forget and try to print or
decode the string as utf8 later.

I know that by convention Go string contain UTF-8 encoded text.
Is it recommended/a good practice to store invalid bytes in a string ?
The use case:
- compute a hash => get a []byte
- convert the []byte to string (this string is not UTF-8 valid)
- use the string as a map key
In my case, the hash
