well, i was thinking of combining Mr. Haines  idea with Mr. James to
get #store_new, which seemed just about right. but now your suggestion
is quite interesting. at first i wasn't so sure, but thinking about it
a little more it makes sense -- "is something stored with this key? if
not store this value with it". i was also worried that it did not
return the stored value like the normal store, but i realize now that
could be ambigious if value=nil, so you may be on point. is that right?
 if so then i have to go with your suggestion.
