Great foresight on my part there, eh? ;-)

I'd be curious to know what others think of Rich's patch. If it is acceptable,
I can spend time that I was going to look at it this week on another bug.

Yes: The change set (svn -c46441) also contains the following NEWS entry
BUG F
When optim() is used with method="BFGS", the name of parameters within
the vector are transmitted (see below, first example).
When method="Brent", the name of parameter (only one parameter can be
fitted with Brent method) is not transmitted. As there is only one, of
course, we know which paramete
This seems to be due to changes made by Martin Maechler in 2008. Presumably
this fixed something, but it escapes my memory.
However, it seems to have broken the equivalence between within.list and
within.data.frame, so now

The crux of the mat
The behaviour of within() with list input changes if you delete 2 or more
variables, compared to deleting one:
l <- list(x=1, y=2, z=3)
within(l,
{
rm(z)
})
#$x
