Hi,
why is this code failing?
class B(object):
pass
B.testattr = property(lambda s:"hallo")
b = B()
b.testattr = "test"

====================================
b = B() # synonyms
When B.testattr = "hallo" so does b.testattr
So if in subsequent code:
B.testattr = property(lambda s:"test")
Then:
b.testattr yields "test"
unless b was essentially destroyed/reused in between times
this is how/why things like:
gc = damn-lot-of-typing-due-to-long-names
gc.something
works as if it was:
damn-lot-of-typing-due-to-long-names.something
