accessing and preserving list names in lapply

res <- lapply(1:length(L),do.one)

Actually, I do

res <- lapply(:length(L),function(x)do.one(L[x]))

-- this is the price of needing the element's name, so I have to both 
make do.one extract the name and the meat separately inside, and 
lapply becomes ugly.  Yet the obvious alternatives -- extracting the 
names separately, attaching them back into list elements, etc., -- are 
even uglier.  Something pretty? :)
