I think I need explain what exactly I need this for. I'm making a
Pascal bridge to Cocoa and it would be convenient if I could pass a
CF type or a Pascal wrapper indiscriminately and decide at runtime

wrapper, because it was created from a CoreFoundation function) I
would not dereference the object and cause crashing.
Hi Ryan
Would the Pascal wrapper be a custom subclass of NSArray which has
some specific functionality for the bridge? I'm trying to
understand how this wrapped array would be different from another
array. As Ali said, it would be better if you could avoid the test.
The wrapper is simply a Pascal object that encapsulates a Cocoa
object. The underlying object is exactly the same as it appears in
Cocoa, except it's accessed via Objective-C runtime functions. The
fact it's a "wrapper" is really not important, I will be testing a CF
type or the underlying Cocoa object.
I'm prepared to abandon this if it's going to dangerous, it would just
be nice if users didn't have to choose manually. Thanks.
Thanks!
Mark
