Serhiy Storchaka <storchaka+cpyt...@gmail.com> added the comment:
The tests are passed because this modification does not affect behavior, it
just makes the code slightly less efficient. Replacing i+1 with i just adds one
iteration:
b = bases[i] # == self
if isinstance(b, _BaseGenericAlias) and b is not self:
return ()
Since b is self, the condition is always false.
It is impossible to catch this change in tests because both codes are
equivalent.
