with the current syntax L[i:i+1] returns [L[i]], with nxlist it returns L[i+1] if i<0.
L=range(10) L[1:2]==[L[1]]==[1] L[-2:-1]==[L[-2]]==[8] L=nxlist(range(10)) L[1:2]==[L[1]]==[1] L[-2:-1]==[L[-1]]==[9] # not [L[-2]] IMHO in this case current list slicing is more consistent. -- http://mail.python.org/mailman/listinfo/python-list
