----------------
As far as I understand, we need to do the double lookup (`find` and later 
`try_emplace`) because we do not want to allocate + take ownership when we hit 
the cache.  An alternative is to first do `try_emplace` with a `nullptr` and 
overwrite the value if the emplace was successful. But I guess that also can be 
confusing, so it is up to you which one would you prefer.
