Yes.  I am sorry my question was not clearer.
There are *many* parameters,
and the list can change,
so I want to avoid listing them all in the Param class's __init__ function,
using the strategy above.

Q1: Is this approach reasonable?
    (This is a newbie question about unforseen hazards.)
Q2: Is it horrible design to isolate the parameters in a separate class?
    (Comment: currently several classes may rely on (parts of) the same
parameter set.)

Thanks,
