Depending on what you do with the index in the loop, it's simple
enough to use the names of a list instead of the indexes.  For
example, you can use the part of the list identified by its name
without needing to know what its index is.

for(i in names(xx)){
  do.something(xx[[i]], ...)

But if it's the index you need, the answer would be No.
