like perhaps `fit[K](X:drmLike[K],T:drmLike[K], (Symbol,Any)*):Model` where
the optional list is hyperparameter list. Then hyperparameterized calls could
be something like: ```
fit(X,Y, 'alpha ->10.0, 'lambda -> 1.e-15)
``` etc.
This loses strong type-iness of the signature but call is not that ugly,
and it might be ok if specific implementations are cleanly documented .
