My personal naming convention is not yet stable, but I currently favour
foos(). I think iterkeys() etc. were only introduced because there already
were methods like keys() returning the corresponding list.
These I now tend to omit and instead make it explicit when I need a list, e.
g.

alltags = list(parser.tags())

and instead of parser.filtertags(pred):

sometags = [t for t in parser.tags() if pred(t)] 

When all returned sequences are iterators, a special prefix/suffix seems
pointless and you may wonder how to name the few exceptions:

list_foo(), foo_list(), listfoo(), foolist(), foos(), ...

:-)
