or somebody is just sloppy. But neither work as expected
right now. (Hint: Consider the return values of each)
I fail to see the bug.
process_line() mutates its `hist` argument, so there's no need to return
something. Or did you mean something else that escapes me?
Oops, no, you are right, I forgot it's mutable. I don't
like that style but that is not a bug...
I was expecting to see a hist = process_line(...)
and a return hist in there...
My bad.
