numerical differentiation?

[Brian Gough]

Yes, that would be very useful, especially if there is an estimate of
the error in the derivative.

Don't feel constrained by omissions in the TODO file -- it is not an
exhaustive list.  As a general rule anything that's covered by
existing proprietary libraries is desirable for GSL.
