This use-case was broken in commit 529cb267a6843a6a8190c86b75d091771d99d6a9 of 2010-10-21, in which I commented "For the moment, we just forbid such matching. We might later wish to insert an automatic downcast to the underlying array type, but such a change should also change matching of domains to ANYELEMENT for consistency". We still lack consensus about what to do with ANYELEMENT; but not matching ANYARRAY is a clear loss of functionality compared to prior releases, so let's go ahead and make that happen. Per complaint from Regina Obe and extensive subsequent discussion.
