Follow-up Comment #14, bug #39713 (project gsl):
Concerning API changes, in my opinion, the implementation
of the secant method should be rewritten to avoid
requirement of the function derivative, that is actually
computed on the first step only. It is enough to
supply two starting points in the beginning. It may be
hard to determine the derivative or to implement
its calculation.
Finally, a note on Python. Some people do not trust it
for the following reason. Supporting of a long-lasting
project e.g. in scientific research may be a real pain
due to API changes.
