In the first one, it's easy to see that there are 4 identifiers. But,
at least for me, the second one is significantly harder to read;
spaces and underscored are too similar. So, while underscores more
clearly separate words in a single *identifier* and make it easier to
read, in some cases I think they make *code* with many identifiers
harder to read for exactly the same reason.

In languages where function application looks like "f(x,y,z)" instead
of "f x y z" this isn't a problem and I often use underscores.
