Object, perhaps? Just a guess, but if you are
interested in the obarray in general I remember asking
about it way back - because as I recall, the
documentation was cryptic to say the least - and there
were some very advanced replies, as I remember. So hit
the archives, look for Emanuel Berg and "obarray" in
the Subject header. Report back everything you learn :)

As I recall, the obarray is a data structure (some kind
of hash table) to store stuff dynamically (i.e., not
just in memory) so that you can filter and do stuff
with it - for example, to provide the set of operands
possible after you invoke a command.
