I'd like to get a list that looks like this:
1. Text addressing #1. 2,3. Text addressing #2 and #3 together. 4. Text addressing #4.
The motivation is that the list items are referring to a previous list. Any idea on how to do this easily with enumerate? (Or some other way to do it that looks consistent with the enumerate environment, i.e. if I had an enumerate list right above it, the two would seem to be formatted identically except the 2,3 part..)
