the constant is used, and python is already slow enough. Maybe a check
that is disabled when running with optimizing flags ?
But I'm sure this discussion has been already made and the FINAL WORD has
been already spoken.

One idea to make constants possible would be to extend properties to be
able to exist at the module level as well as the class level:
@property
def pi():
return 3.14159.....
print(pi) # prints 3.14159....
pi=32 # Raise an error Cannot set attribute ...
I don't understand why this would print 3.14159 ... instead of <function
__math__.pi>, or whatever.
property would clearly have to do something very different in module
scope in order to make this work.

--> class tester(object):
... @property
... def pi(self):
... return 3.141596
...
--> testee = tester()
--> testee.pi
3.1415959999999998
Looks like that's how property works, so the same behavior on a module
level would do as Brian suggests.
