I've been stung by opaque objects a couple times:
1) when the method comes from calculation via __getattr__ type methods
class Foo(object):
def __getattr__(self, attr):
if attr.startswith("say_"):
utterance = attr[4:]
def method():
return "Hello, %s" % utterance
return method
f = Foo()
f.say_Bob()
dir(f) # no "say_Bob" method
2) when the underlying object is written in C and doesn't expose the
dir() properly (I'm looking at mod_python's objects in particular
which didn't allow inspection the last time I used it; though in
fairness, this was 7-9yrs ago)
