[SciPy-User] scipy.optimize named argument inconsistency

I'm glad to see that several people agree on this topic. I will then
work on standardizing names and orders of parameters and returns
as well as possible grouping (e.g. for solver statistics).

I guess the case input parameters could be treated by adding new
parameters and pointing old ones to the latter with a warning. But what
about returns? For instance, how should one deal with changes of order
or parameters being grouped with others?

In general, I have little knowledge concerning deprecation mechanisms so
any advice (or documentation/example pointer) would be welcome.
