I still don't understand this issue.  For a small playground, drawing
another way in order to tag the area as a playground isn't so bad, but
for a larger thing, it seems quite tedious to re-draw each meaning of
the way- as well as inaccurate.  If the fence is irregular, and has
been mapped carefully, it seems like it would be more accurate and
easier to somehow copy the way that is the fence, add the last side,
and tag it as the playground boundary.  Is there a way to duplicate
ways and re-tag them with a different attribute?

(I am afraid the terms I'm using aren't quite correct... I hope my
meaning has come across).
