del Params # hide the class
Then callers just say:
from params import params
print params.c
I'd replace the instantiation & deletion of the class in params.py with:
import sys
sys.modules[__name__] = Params()
..and replace the module itself with the parameter object. I'd also add:
__file__ = __file__
...to the class definition to help with debugging. But this is really
just bikeshedding.
It's a shame the property decorator doesn't work at the module level,
though.
