Indeed. Sorry, I'm afraid I gave you bad advice wrt/ using a
staticmethod here - I should know better :( (well, OTHO staticmethods
are not something I use that often).
Do not worry the least bit! I'm testdriving on a closed circuit here for
sake of becoming better 'driver', I'm not going to drive like this on
the streets.

Well I could always do:
if isinstance(self.tagada['bar'], staticmethod):
self.tagada['bar'].__get__(self)(baaz)
else:
self.tagada['bar'](baaz)
But 1. this apparently defeats the purpose of using print_internal_date
on instance/class in 'normal' way, and 2. I probably shouldn't be doing
that since using isinstance is apparently like playing with yourself:
while technically legal, people look at you weirdly. :-)

def bar(baaz):

Neat! I like this one.
class Foo4(object):

@staticmethod
def bar(baaz):
print baaz
tagada = {'bar': lambda x : Foo4.bar(x)}
def test(self, baaz):
self.tagada['bar'](baaz)
Huh? How does this one work? After all, while in Foo4 body, the Foo4
does not exist yet? Does lambda defer evaluation to runtime (when it's
executed) or smth?

def foo5bar(baaz):

Yes. I probably should have stayed with this one in the first place. I
feel bad for using up bandwidth and people's attention with such stuff...
