## install
``` cmd
pip install singletonify
```
## usage
``` py
@singleton(a=3)
class YourClass:
def __init__(self, a): ...
assert YourClass() is YourClass()
```
## why not other
There are many singleton libraries on pypi, but their all has problem:
* [singleton](https://pypi.python.org/pypi/singleton) - cannot use `issubclass()` or `__mro__` or ...
* [singleton-decorator](https://pypi.python.org/pypi/singleton-decorator) - cannot use `isinstance()` .
* [singleton_factory](https://pypi.python.org/pypi/singleton_factory) - wtf, why do people use `dict()[hash(obj)] = obj` ?
* [singletonmetaclasss](https://pypi.python.org/pypi/singletonmetaclasss/0.1) - a little like this, but not a decorator.
* [singleton3](https://pypi.python.org/pypi/singleton3) - haha
* [pysingleton](https://pypi.python.org/pypi/pysingleton) - ABANDONED.
