Gilles Sadowski commented on MATH-1656:
---------------------------------------
Hi.
Before being diverted, I performed several local changes, following the
discussion about incremental modification and overall current design of the
"optim" package. I'm afraid that your new patch will likely be quite
incompatible with what I intended to commit. I'll try to sort that out ASAP,
and we'll then resume from there. Sorry for the inconvenience!
