The slice() list VMethod suggests you can use negative indices to count "backwards" from the end of the list. It doesn't quite work as expected if one index is positive but the other negative. For example, I wanted all but the first and last elements:
list.slice(1, -1)
This in fact always returns an empty list.
This can be fixed by:
