@davies I really want to force user to use named arguments because it is
really hard to determine what is the right ordering of those parameters. I saw
a slightly hacky solution here for Python 2
(http://stackoverflow.com/questions/2965271/forced-naming-of-parameters-in-python):
~~~python
__named_only_start = object()
def info(param1,param2,param3,_p=__named_only_start,spacing=10,collapse=1):
if _p is not __named_only_start:
raise TypeError("info() takes at most 3 positional arguments")
~~~
If you feel this is too hacky, this is the ordering I would recommend:
`data, numIterations, initialWeights, regParm, regType, intercept, corrections,
tolerance`.
