question of style
Hey I was hoping to get your opinions on a sort of minor stylistic
point.
These two snippets of code are functionally identical. Which would you
use and why?
The first one is easier [for me anyway] to read and understand, but
slightly less efficient, while the second is [marginally] harder to
follow but more efficient.

## First snippet

if self.higher is self.lower is None: return
if self.lower is None: return self.higher
if self.higher is None: return self.lower

## Second snippet

if self.higher is None:
if self.lower is None:
return
return self.lower
if self.lower is None:
return self.higher

What do you think?

(One minor point: in the first snippet, the "is None" in the first
line is superfluous in the context in which it will be used, the only
time "self.lower is self.higher" will be true is when they are both
None.)
