... although it seems that the interface in Scipy now is a much more
lower-level one --- and does not have the parameter convenience
abstraction, which seems to be the main point in lmfit, and is
orthogonal to what's currently in. Now that would be a rather useful
addition, one just would have to figure out how to make it work nicely
also with the scalar optimizers.
