That's cos Smalltalk returns 'self' by default when a there is no explicit
return value. This can be done in Python if your 'set' methods return 'self'
instead of 'None'. For example:
>>> class A:
def m1(self, t1):
self.t1 = t1
return self
def m2(self, t2):
self.t2 = t2
return self
def m3(self, h, w):
self.h = h
self.w = w
return self
>>> a = A().m1("Hello World").m2("window").m3(400,200)
>>> a.h
400
