<div>Hi Spencer,</div>
<div><br></div>
<div>Something that bugged me in the past as well. It would be
nicer to have everyone inherit from a single point, but since Atoms
don't have children, it would be confusing to have these methods
there. My understanding is that Entity only exists to provide
methods to handle iteration over children objects. It's a
compromise?<br></div>

<div style="font-family:Helvetica,Arial;font-size:13px">I was
wondering why Atom doesn't inherit from Entity. It doesn't have
children, but it seems like it would be more consistent to have the
whole Structure stack inherit from a single point. Is anyone aware
of the history there?</div>

<div style="font-family:Helvetica,Arial;font-size:13px">I ask
because I'm trying to add type annotations to Bio.PDB, and mypy
flagged a number of places where my initial 'Entity' type
conflicted with Atoms. We can certainly get around this by
accepting either Entity or Atom, but I'm not sure that was
intended.</div>
