pylint #107062 "E1101: %s %r has no %r member" should take a hint from hasattr [open]

In the following code, we take care to check the existence of a dynamic attribute
before accessing it, but still, pylint issues a false positive:

E: 3,38:A.argh: Instance of 'A' has no 'blurb' member

---- 8< ----
class A(object):
def argh(self):
if hasattr(self, "blurb") and self.blurb:
print "yes"
else:
print "no"

    Similarly, E1102 can trigger, calling something non-callable, when the call is protected by a callable() test:

    E: 6,19:A.foo: x is not callable

    ---- 8< ----
    x = None

    class A(object):
    def foo(self):
    if callable(x):
    return x(0)
    else:
    return x
