In general, nope. The array, for example, may contain dictionaries,
each of which can have any set of keys, determined dynamically at
runtime.

In some particular cases it may be possible (and I believe the future
IB releases would be smarter doing that :) -- generally, if you know
the class of the objects inside the array, you can use the runtime
information to get the methods (and you can deduce which ones could be
used for keys through their signatures).
