Actually you might want to have a couple of instances with different
__init__ params:
---- 8< ----
from threading import local, Thread
class View(object):
_child = local()
def __new__(cls, *args, **kwargs):
if not hasattr(cls._child, 'dict'):
cls._child.dict = {}
param_hash = (args, tuple(kwargs.items()))
existing = cls._child.dict.get(param_hash, None)
if not existing:
print 'first time in this thread with args', param_hash
cls._child.dict[param_hash] = super(View, cls).__new__(cls)
return cls._child.dict[param_hash]
def __call__(self, foo):
print 'call', id(self), foo
return 'bar'
