Sorry, I meant &&: `IsPythonObjectValid() && Base::IsValid()`. Basically, I'm
trying to see if there's a reasonable way to reduce the number of classes
floating around, and this `PresumptivelyValidFile` seems like it could be
avoided...

There's no need to put a semicolon after the body of the constructor.

Are you sure you're looking at the right place (the comments tend to move
around as you reorganize code)? I was asking why is PythonFile a friend of the
BinaryPythonFile class. That doesn't seem relevant to the PyErr_Occured
checks...
