Object Pascal typing is based on name equivalence; however, untyped
pointers (Pointer) are compatible with objects (TObject &
descendants), which is pretty miserable.

though, and they aren't descendant from TObject (but they aren't
"objects" either).

"Obscure"? That's a pejorative term. Perhaps you'd like to expand.

RAD is very good for GUIs; that's about it.
