Yes!

Will revise the patch accordingly
and use Just's suggested name, fromseq().

Do you prefer the default value to be None or True?
Earlier discussions on python-dev showed that
True is more meaningful to some in the context of
membership testing.  OTOH, dict.setvalue and 
dict.get both use None.
