++ablankst that byte isn't special here. Brad singled out []byte/string because those are the types stored in groupcache (see ByteView in the groupcache code for his sneaky tricks to make them look the same to other code).

And yes, unfair to ask someone to test every guess they have. But if you do want to know a bit more about what effect GC and Go would have, experimenting with toy programs isn't a bad way to get a feel.
