nl - numbering input in descending order

Is this possible to number file lines in descending order? That would be something like: nl -i -1 unfortunately this gives me: nl: invalid line number increment: ‘-1’: Numerical result out of range I know that it has no sense in pipe redirection, as nl can't guess number of total lines, but if I pass file as an argument it should be quite easy - even it it needs two passes to accomplish the task. If not nl than maybe some other command.
