Oh, if they're connected on THAT level then there really is no way. So
NSArray is a wrapper for CFArray? ;) If the Runtime Wrangler says it
can't be done, it probably can't be done. Thanks for clearing this up.

There is not. For example, [NSMutableArray array] calls
CFArrayCreateMutable() to do the work, returning an array that's
indistinguishable from the one you get if you call
CFArrayCreateMutable() directly.
#0 0x93628d13 in CFArrayCreateMutable ()
#1 0x9366c0ff in -[__NSPlaceholderArray initWithObjects:count:] ()
#2 0x93679c24 in +[NSArray array] ()
Even if you could find some distinguisher, it would almost certainly
be unsupported and behave differently in past or future OS versions.
