Not really, no: in the docstring of `seq-mapn` what we want to show to
the user about the above method is when it applies, i.e. its
"specializers".  We could try to make it say that the specializer is
"all args after `function` are of type `stream`", but there's no
standard format to express that.  We could invent one, like

    (seq-mapn FUNCTION &rest (STREAMS (list stream)))
or
    (seq-mapn FUNCTION (STREAM stream) ...)

but it seems like more trouble than it's worth.
