I dunno, but the example also tells something essential: that the
mapping happens in a delayed way.  That, and the implications, might not
be obvious.  Maybe it's not wrong to have that in a docstring - maybe
even more explicit than currently?

I'm also looking at the doc of `seq-map's implementation in stream.el.
