Note that, while convention is to use a symbol for property names, that
is not the only valid choice.  0 is a valid property name (tho an odd
one, arguably).

So while this 0 should probably be changed the mapconcat code that burps
on it should probably be changed not to assume that only symbols will
be used as property names.
