Coding style in CPython implementation

[ROGER GRAYDON CHRISTMAN]

NOTE:   The case in question was never comparing to True;  it was comparing to
NULL.

There is no "No: if x == None" below, because None is not Boolean.
Similarly comparing a pointer to NULL is not the same as comparing it to a
Boolean.

So I would favor the "Explicit is better than Implicit" in the example cited.
