True. Perhaps my assumptions are wrong again.
I am assuming that it loads only the required functions dynamically. The example given to show why to preload was for Enum.map.
1.15 enabled code pruning, so I also assume that is the function, not module level?
Then on disk the beam files only take 30MB, but code. taking 50MB. 
Suffice to say, I don’t understand the internals.
