I just wanted to bring to your attention that an *attribute for removing
duplicate elements* for lists would be a nice feature.

*def uniquify(lis):
    seen = set()
    seen_add = seen.add
    return [ x for x in lis if x not in seen and not seen_add(x)]*
The code is from this
check out this performance
comparison<http://www.peterbe.com/plog/uniqifiers-benchmark> of
uniquifying snippets.
It would be useful to have a uniquify attribute for containers in general.

Best regards, Robrecht
